Homework Statement
If a, b and c are positive integers with (a,b) = 1 and c2 = ab, show that each of a and b is the square of an integer.
I've been staring at this problem for a while now and I've got not clues. I don't see the relation between a and b being relatively prime and the rest of the problem. Any hints would be appreciated
