Any number is said to be divisible by 12 if that number is divisible by 3 as well as 4 (remember, 12 can be written as 3 x 4). If the number is not divisible by either of 3 or 4, then the number is not divisible by 12.

To check divisibility by 3, please refer to topic Divisibility by 3.

To check divisibility by 4, please refer to topic Divisibility by 4.

For example: Is 34548 divisible by 12?

Step 1: Sum of digits of 34548 is (3+4+5+4+8=) 24.

As 24 is divisible by 3, so number 34548 is divisible by 3.

Step 2: Last 2 digits of 34548 is 48.

As 48 is divisible by 4, i.e. 48 **÷ **4 = 12, so number 34548 is divisible by 4.

As number 34548 is divisible by 3 and 4, both, so this number is divisible by 12.
