WebFor the proof of correctness, we need to show that gcd ( a, b) = gcd ( b, a mod b) for all a ≥ 0, b > 0. We will show that the value on the left side of the equation divides the value on the right side and vice versa. Obviously, this would mean that the left and right sides are equal, which will prove Euclid’s algorithm. Let d = gcd ( a, b). WebIn arithmetic and computer programming, the extended Euclidean algorithm is an extension to the Euclidean algorithm, and computes, in addition to the greatest common divisor (gcd) of integers a and b, also the coefficients of Bézout's identity, which are integers x and y such that + = (,).

http://duoduokou.com/algorithm/61072705954916177913.html WebThe Binary GCD Algorithm In the algorithm, only simple operations such as addition, subtraction, and divisions by two (shifts) are computed. Although the binary GCD algorithm requires more steps than the classical Euclidean algorithm, the operations are simpler. The number of iterations is known [6] to be bounded by 2 (\log_2 (u)+\log_2 (v)+2).
