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
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
