how to calculate gcd

Calculate the maximum common divisor of two numbers A and B. We can think of enumerating each positive integer from [1, min (A, B: #includeusing namespace std;int gcd(int a,int b){ int ans=1; for(int i=2;i>a>>b; cout   However, when a and B

Extended Euclidean algorithm-solving indefinite equation, linear congruence equation.If the two frogs meet after the S-step, the following equations will be fulfilled:(x+m*s)-(y+n*s) =k*l (k=0,1,2 ...)Slightly changed to form:(n-m) *s+k*l=x-yMake

Euclidean Algorithm gcd and its ultimate explanation This problem has plagued me for a long time. I finally found an explanation, and I made some changes myself. I will certainly be able to deepen my understanding after my patience.  Extended

The following snippet is copied from the book (structure and interpretation of computer programs 1.2.5) ----------------------------------------------- The greatest common divisor (GCD) of two integers A and B is defined to be the largest integer

This function is a good one I accidentally saw. It is awesome and I like it. Is used to find the minimum public approx. A simple description is that gcd (a, B) indicates the maximum public factor of non-negative integers A and B, so: gcd (a, B) =

Gcd () --- indicates the maximum common number. The common method is Euclidean algorithm. Ex_gcd () --- Extended Euclidean Algorithm Definition 1: A and B are two integers not all 0, that is, the maximum common divisor of A and B is the maximum
