Edit: Ummmm... You might need to see if this is the correct question. m = 4 gives 4^2 = 16 is divisible by a = 8. But 4 is not divisible by 8.

I believe what was intended is that "if is divisible by prime number a then n is divisible by a". The simplest way to prove that is to look at the prime fatorizations of n and .
