#include<stdio.h>
int gcd(int m,int n){
if(m==n)
        return m;
    else{
        while(1){
            if(m>n)
                m=m-n;
            else if(m<n)
                n=n-m;
            else
                return m;
                break;
        }
    }
}
int main(){
    printf("%d\n",gcd(7,32));
    return 0;
}
这个怎么不能求到最大公约数,错在哪?

谢谢!!!什么原理啊???

我发现这样也行: else{
                   return m;
                   break;
                }
