One way to find if a number is divisible by 3 without actually doing the division is to add up the digits of the number until you get 1 digit then if this number is 3,6 or 9 then the number is divisible by 3.

For example 137: - 1 + 3 + 7 = 11. 1 + 1 = 2 - so not divisible by 3.

The answer here : - 60 is the only one divisible by 3.
