## Divisibility by 3

In this page divisibility by 3 we are going to see,how to check whether the given number is divisible by 3 or not.Whenever we need to check whether the given number is divisible by 3 or not.Fist we have to calculate the sum of the digits.If the sum of the digits is divisible by 3.Then we can say it is divisible by 3.In other wards we can say a number is divisible by 3 if the sum of the digits is divisible by 3.

Example 1:

Test whether 252 is divisible by 3?

Solution:

To check whether it is divisible by 3 or not we have to calculate the sum of the digits.

252 = 2 + 5 + 2

= 9 ÷ 3

= 3

Example 2:

Test whether 1326 is divisible by 3?

Solution:

To check whether it is divisible by 3 or not we have to calculate the sum of the digits.

1326 = 1 + 3 + 2 + 6

= 12 ÷ 3

= 4

Some more examples on divisibility by 3.

Example 3:

Test whether 6471 is divisible by 3?

Solution:

To check whether it is divisible by 3 or not we have to calculate the sum of the digits.

6471 = 6 + 4 + 7 + 1

= 18 ÷ 3

= 6

Example 4:

Test whether 487 is divisible by 3?

Solution:

To check whether it is divisible by 3 or not we have to calculate the sum of the digits.

487 = 4 + 8 + 7

= 19

Here the number 19 is not divisible by 3.So we can say the given number 487 is not divisible by 3.
