Multiple of a natural number course & worksheets

A multiple of a natural number is the product of that natural number with another natural number.

In other words, to find a multiple of a natural number, you must multiply that number by another natural number.

Example: 10 is a multiple of 5 because 10 =  2 ×5

40 is a multiple of 5 because 40 = 5 × 8

4670 is a multiple of 5 because 4670 = 5 × 934

Multiple of a natural number formula

The formula to find the multiple of a natural number is:

Multiple = Natural Number × Another Natural Number

In mathematical notation, you can represent this as:

Multiple = N × M

Where:
– “Multiple” is the result, which is a multiple of the natural number.
– “Natural Number” is the given natural number for which you want to find a multiple.
– “Another Natural Number” is any other natural number that you choose to multiply with the given natural number to find its multiple.
– “N” represents the given natural number.
– “M” represents the other natural number you choose for multiplication.

For example, if you want to find a multiple of 7, you can choose any other natural number, say 3, and use the formula:

Multiple = 7 × 3 = 21

So, 21 is a multiple of 7, and you can use this formula with different values of “M” to find various multiples of 7.

 

Properties

1- Zero (0) is a multiple of any natural number.

0 × n = 0 for any n

Example: 0 = 0 × 37

2- Every natural number is a multiple of 1.

n = 1 × n

Example: 29 = 1 × 29

3- Every natural number is a multiple of itself.

n = n × 1

Example: 67 = 67 × 1

4- The sum of two multiples of the same natural number is a multiple of that natural number.

Example: 12 = 3 × 4 12 is a multiple of 3

18 = 3 × 6 18 is a multiple of 3

The sum of the multiples: 12 + 18 = 30

30 = 3 × 10 30 is a multiple of 3

5- The difference between two multiples of the same natural number is a multiple of that natural number.

Example: 36 = 3 × 12 36 is a multiple of 3

21 = 3 × 7 21 is a multiple of 3

The difference of the multiples: 36 – 21 = 15

15 = 3 × 5 15 is a multiple of 3

Note: A natural number has an infinite number of multiples.

 

Multiples of 1

Multiples of 1 are relatively straightforward since any number multiplied by 1 remains the same. Therefore, the multiples of 1 are all the positive integers. In other words, every natural number is a multiple of 1.

1 × 1 = 1  1 × 2 = 2  1 × 3 = 3  1 × 4 = 4   1 × 5 = 5

 

Multiples of 2

A multiple of 2 is any number that can be evenly divided by 2 without leaving a remainder. In other words, if you can divide a number by 2 and get a whole number as the result, then that number is a multiple of 2.

Examples of multiples of 2 include:

– 2
– 4
– 6
– 8
– 10
– 12
– 14
– 16
– 18

Multiples of 3

A multiple of 3 is a number that can be divided by 3 without a remainder. For example, 3, 6, 9, 12, and 15 are all multiples of 3.

There are a few ways to determine if a number is a multiple of 3. One way is to simply divide the number by 3 and see if the remainder is 0. If the remainder is 0, then the number is a multiple of 3.

Another way to determine if a number is a multiple of 3 is to add up the digits of the number and see if the sum is divisible by 3. If the sum is divisible by 3, then the number is also divisible by 3. For example, the number 12 is a multiple of 3 because 1 + 2 = 3, and 3 is divisible by 3.

Here are some examples of multiples of 3:

  • 3
  • 6
  • 9
  • 12

  • 16
  • 20
  • 24
  • 28
  • 32
  • 36
  • 40

To identify multiple of 4. One way is to use the following divisibility rule:

A number is divisible by 4 if the last two digits are divisible by 4.

For example, the number 124 is a multiple of 4 because the last two digits, 24, are divisible by 4.

Another way to identify multiples of 4 is to use the following divisibility rule:

A number is divisible by 4 if the sum of the digits is divisible by 4.

For example, the number 124 is a multiple of 4 because the sum of the digits, 1 + 2 + 4 = 7, is divisible by 4.

Multiples of 5

11, 22, 33, 44, 55, 66, 77, 88, 99, 110, 121, ...

To find if a number is a multiple of 11, you can use the following steps:

  • Add the digits in the even places of the number.
  • Add the digits in the odd places of the number.
  • Subtract the smaller sum from the larger sum.
  • If the difference is divisible by 11, then the original number is also divisible by 11.

For example, the number 121 has a sum of digits of 4, which is divisible by 11, so 121 is a multiple of 11.

20, 40, 60, 80, 100, 120, 140, 160, 180, 200, ...

To determine if a number is a multiple of 20:

  • Look at the last two digits. If the last two digits of a number are divisible by 20, then the number is divisible by 20. For example, the number 120 is divisible by 20 because the last two digits, 20, are divisible by 20.
  • Divide the number by 20. If the number can be divided by 20 without leaving a remainder, then the number is a multiple of 20. For example, the number 100 is a multiple of 20 because 100 ÷ 20 = 5.
  • Use the prime factorization of 20. 20 is a product of the prime numbers 2 and 5. Therefore, in order for a number to be a multiple of 20, it must have at least two factors of 2 and one factor of 5. For example, the number 100 is a multiple of 20 because it has two factors of 2 (2 × 2 = 4) and one factor of 5 (100 ÷ 5 = 20).

you can also use the following steps to determine if a number is a multiple of 21:

  • Divide the number by 3.
  • Divide the result by 7.
  • If the result  is an integer, then the number is a multiple of 21.

For example, to determine if the number 126 is a multiple of 21, we would do the following:

  • Divide 126 by 3: 126 ÷ 3 = 42
  • Divide 42 by 7: 42 ÷ 7 = 6
  • The result of step 2 is an integer, so 126 is a multiple of 21.

Another way to determine if a number is a multiple of 21 is to add up the digits of the number. If the sum of the digits is divisible by 3, then the number is also divisible by 3 and therefore a multiple of 21. The number 126 is a multiple of 21 because 1 + 2 + 6 = 9, and 9 is divisible by 3.

Multiples of 25

Multiples of 25 are numbers that can be divided by 25 without a remainder.

25, 50, 75, 100, 125, and so on

To determine if a number is a multiple of 25, there are a few things you can do:

  • Look at the last two digits of the number. If the last two digits are 00, 25, 50, or 75, then the number is a multiple of 25.
  • Divide the number by 25. If the number is divisible by 25 without leaving a remainder, then the number is a multiple of 25.

  • The number must be even.
  • The sum of the digits in the number must be divisible by 3.

Examples:

  • The number 60 is a multiple of 30 because it is even and the sum of its digits (6 + 0 = 6) is divisible by 3.
  • The number 90 is a multiple of 30 because it is even and the sum of its digits (9 + 0 = 9) is divisible by 3.
