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 … WebIt states that for each pair of integers ( a, b) there is an integer solution to this equation: If we divide ( a + b) x + b y = gcd ( a + b, b) by gcd ( a + b, b) the RHS will be 1.
