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)

 

 

cool cool cool
