WebThe extended Euclidean algorithm is an algorithm to compute integers x x and y y such that. ax + by = \gcd (a,b) ax +by = gcd(a,b) given a a and b b. The existence of such integers is guaranteed by Bézout's lemma. The extended Euclidean algorithm can be viewed as the reciprocal of modular exponentiation. By reversing the steps in the … WebUnderstanding the Euclidean Algorithm. If we examine the Euclidean Algorithm we can see that it makes use of the following properties: GCD (A,0) = A. GCD (0,B) = B. If A = B⋅Q + R and B≠0 then GCD (A,B) = GCD (B,R) where Q is an integer, R is an integer between 0 and B-1. The first two properties let us find the GCD if either number is 0.
