WebMar 25, 2016 · Why do you say its O(log(smaller number))? As I see the algorithm, the bigger number is reduced by at least half in every two iterations. So I said its O(log(bigger number)). WebMay 15, 2013 · This is a major open question in complexity theory: it is not known if GCDs can be computed in NC, and it is not known if computing GCDs is P-complete. The best parallel algorithms do have sub-linear parallel running time, one such algorithm being due to Sorenson: J. Sorenson. Two fast GCD algorithms. Journal of Algorithms, 1994.

WebTime Complexity. The time complexity of the algorithm is of the order O(log(min(a, b))). Space Complexity. The program consumes an extra space O(1) for the both the iterative and recursive version (because of tail recursion). Extended version of Euclid's Algorithm WebFeb 22, 2024 · If a and b are N bits long, then in the worst case (Fibonacci pairs), the extended Euclidean algorithm will take O (N) iterations. Let f (N) be the cost of a single iteration. Certainly f (N) will be at least linear, but …
