How can you tell if 342 is divisible by 3?

Answer 1

Divide it by 3. In this case, 342 IS divisible by 3, because we get 114 instead of a fraction.

And the quicker way is: Add the digits: 3+4+2 = 9

If the sum of digits is divisible by 3 then the number is divisible by 3. 9 is divisible by 3 so is 342.

Answer 2

To determine if 342 is divisible by 3, you can add up the digits of the number: 3 + 4 + 2 = 9. If the sum is divisible by 3, then the original number is also divisible by 3. In this case, since 9 is divisible by 3, 342 is also divisible by 3.

Answer 3

The sum of its digits is a multiple of 3, so 342 is a multiple of 3.
