# Converse of DIC

I am looking to prove the converse of the Divisibility of Integer Combination.

I know how to prove the contrapositive of this statement but not the converse ... any help?

Below is my attempt at the solution

• You need to show that a|b. There is no variable 'x' involved. I am not able to understand your doubt! It is given that a|(bx+cy) for all x,y$\in Z$. You need to show a|b, where is the problem? May 28 '14 at 4:03
