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.
