Consider The Factors, Get Perfect Square? (Posted on 2007-09-23) Difficulty: 3 of 5
p, q and r are three positive integers satisfying 1/p + 1/q = 1/r, such that there is no integer ≥ 2 dividing p, q and r simultaneously. However, p, q and r are not necessarily pairwise coprime .

Prove that (p+q) is a perfect square.
