## Divisibility Rule of 7

The concept of divisibility is nothing but checking if a number is divisible by another number without actually dividing the number. The divisibility rule of 7 checks if a number can be completely divided by 7 without any remainder.
Usually, we perform the division arithmetic operation to know this. But divisibility rule of 7 has a shortcut method to find if a number is divisible by 7.

### Divisibility Test by 7 Examples

Have a look at the below examples to know in detail about divisibility by 7 without applying the division method. Let us check if the number is divisible by 7 or not.

Example 1.
Find whether the number 182 is divisible by 7.
Solution:
For divisible by 7 we need to double the last digit of the number and then subtract it from the remaining number. If the result is divisible by 7, then the original number will also be divisible by 7.
Here in 182
2 + 2 = 4
18 – 4 = 14
Where 14 is divisible by 7
Therefore the number 182 is also divisible by 7.

Example 2.
Find whether the number 252 is divisible by 7.
Solution:
For divisible by 7 we need to double the last digit of the number and then subtract it from the remaining number. If the result is divisible by 7, then the original number will also be divisible by 7.
Here in 252
2 + 2 = 4
25 – 4 = 21
Where 21 is divisible by 7
Therefore the number 252 is also divisible by 7.

Example 3.
Find whether the number 595 is divisible by 7
Solution:
For divisible by 7 we need to double the last digit of the number and then subtract it from the remaining number. If the result is divisible by 7, then the original number will also be divisible by 7.
Here in 595
5 + 5 = 10
59 – 10 = 49
Where 49 is divisible by 7
Therefore the number 595 is also divisible by 7.

Example 4.
Find whether the number 343 is divisible by 7.
Solution:
For divisible by 7 we need to double the last digit of the number and then subtract it from the remaining number. If the result is divisible by 7, then the original number will also be divisible by 7.
Here in 343
3 + 3 = 6
34 – 6 = 28
Where 28 is divisible by 7
Therefore the number 343 is divisible by 7.

Example 5.
Find whether the number 672 is divisible by 7.
Solution:
For divisible by 7 we need to double the last digit of the number and then subtract it from the remaining number. If the result is divisible by 7, then the original number will also be divisible by 7.
Here in 672
2 + 2 = 4
67 – 4 = 63
Where 63 is divisible by 7
Therefore the number 672 is divisible by 7.
