Re: divisible byPythagorean triples are of the form where are positive integers with . If one or both of m and n are even, then C is divisible by 4; otherwise they are both odd and so B would be divisible by 4. And in this thread http://www.mathisfunforum.com/viewtopic.php?id=11085 it is proved that 60 divides the product ABC, i.e. 5 (a prime) divides one of A, B, C. #3 20081209 20:14:11
