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).

WebThere 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 two numbers. Prime factorize the two numbers. WebJul 9, 2024 · This way, in each step, the number of digits in the binary representation decreases by one, so it takes log 2 ( x) + log 2 ( y) steps. Let n = log 2 ( max ( x, y)) (maximum number of bits possible), then indeed the overall worst case complexity is O ( n 2), since large numbers subtraction operation take Θ ( log 2 ( N)).
