But then the Bezout's coefficients will be found incorrectly. Let, for example, a < 0, and b > 0. Then after changing the sign of a, the resulting Bezout's identity will look like this: gcd (a, b) = s (-a) + tb (in terms of -a and b) or

WebNov 30, 2024 · What is the Extended Euclidean Algorithm? This is an extension of Euclidean algorithm. It also calculates the coefficients x, y such that ax+by = gcd (a,b) x and y are also known as coefficients of Bézout's identity. c … WebFeb 6, 2024 · Extended Euclidean algorithm finds integer coefficients x and y such that: ax + by = gcd(a, b) Let us put b = prime, we get ax + prime * y = gcd(a, prime) We know gcd(a, prime) = 1 because one of the numbers is prime. So we know ax + prime * y = 1 Since prime * y is a multiple of prime, x is modular multiplicative inverse of a. ax ≡ 1 (mod …
