Binary gcd complexity
The binary GCD algorithm, also known as Stein's algorithm or the binary Euclidean algorithm, is an algorithm that computes the greatest common divisor of two nonnegative integers. Stein's algorithm uses simpler arithmetic operations than the conventional Euclidean algorithm; it replaces division with … See more The algorithm reduces the problem of finding the GCD of two nonnegative numbers v and u by repeatedly applying these identities: 1. gcd(0, v) = v, because everything divides zero, and v … See more While the above description of the algorithm is mathematically-correct, performant software implementations typically differ from … See more The binary GCD algorithm can be extended in several ways, either to output additional information, deal with arbitrarily-large integers more … See more • Computer programming portal • Euclidean algorithm • Extended Euclidean algorithm • Least common multiple See more The algorithm requires O(n) steps, where n is the number of bits in the larger of the two numbers, as every 2 steps reduce at least one of the operands by at least a factor of 2.
