WebJan 14, 2024 · The Binary GCD algorithm is an optimization to the normal Euclidean algorithm. The slow part of the normal algorithm are the modulo operations. Modulo operations, although we see them as O ( 1) , are a lot slower than simpler operations like addition, subtraction or bitwise operations. So it would be better to avoid those. WebAnother name for GCD is HCF(Highest Common Factor). There are three powerful algorithms to find gcd of two numbers: Euclidean Algorithm, Stein’s Binary GCD Algorithm, and Lehmer GCD Algorithm. Among these, the simplest one is Euclidean Algorithm. A straightforward way to find gcd is by comparing the prime factors of the …

WebBinary Euclidean Algorithm: This algorithm finds the gcd using only subtraction, binary representation, shifting and parity testing. We will use a divide and conquer technique. The following function calculate gcd (a, b, res) = gcd (a, b, 1) · res. So to calculate gcd (a, b) it suffices to call gcd (a, b, 1) = gcd (a, b).
