It is widely known that the time complexity to compute the GCD (greatest common divisor) of two integers a, b, using the euclidean algorithm, is . Short proof This bound is nice and all, but we can provide a slightly tighter bound to the algorithm: We show this bound by adding a ...

The time complexity is O(n), utilizing O(n)4-2 signed 1-b adders to determine the GCD of two n-b integers. The process is similar to that used in SRT division. The efficiency of the algorithm is competitive, to within a small factor, with floating point division in terms of the ...
The time complexity for the Euclid algorithm is log(n).Pseudo Code://Euclid gcd function. int gcd(int a,int b) { //if b==0 then return a. if(b==0) return a else return gcd(b,a%b) } The time complexity for the brute force approach in the worst case is O(N) for each ...
