Computing the Greatest Common Divisor

The gcd is 34 53. (b) Compute gcd(22 35;56 7). The two numbers share no prime factors, so the gcd is 1. Computing gcd(a;b) by the Euclidean algorithm. Reference T&W, p. 67. The Euclidean algorithm for calculating greatest common divisors is very simple and fast. It is a descent algorithm in the sense that we will do a sequence of simple opera- ................
