Suppose that gcd(a;bc) = 1 and let gcd(a;b) = d. Thus d divides a and b. Hence d divides a and bc. Therefore d = 1. Similarly gcd(a;c) = 1. Conversely, suppose that gcd(a;b) = 1 = gcd(a;c). Now assume that gcd(a;bc) = d > 1 and we will arrive at a contradiction. Let p be a prime divisor of d. Thus p divides a and p divides bc. By Euclid ... those who bring sunshine to the lives
