What is the least positive integer that can be added to 412 to yield a multiple of 3?

If the sum of a number's digits is divisible by 3, the number is divisible by 3

So

412 + 2 = 414

and

4 + 1 + 4 = 9

So....414 is divisible by 3 (and a multiple of 3)

Thanks! I could have done this, didn't readit well though. Thank you though.
