WebJan 27, 2015 · Let a, b, c ∈ N and a 2 + b 2 = c 2 then a b c is even. My attempt: If one or two numbers of a, b, c are even then we're done, so we'll have to show that at least one of them is even. Suppose a, b are odd, then a 2, b 2 are odd, so a 2 + b 2 must be even. So c 2 is even then c is even. So a b c is even. Is this enough to prove it?
