Date: Sep 9, 2013 4:35 AM Author: Johnson1107 Subject: Greatest common divisor I have some problem with this task. There are three diffrent integer numbers x, y, z greater than 1 and they are relatively prime. Find every possible number value of GCD(a^2*b+b^2*c+c^2*a, a*b^2+b*c^2+c*a^2). I apreciate any hint.
