给邵或的题解

#include <bits/stdc++.h>

using namespace std;

int main() {

int n, m, mx = -99;
cin >> n >> m;
int xx = max(m, n);

for(long i = 1; i <= xx; i++) {
    if (m % i == 0 && n % i == 0) {
        mx = i;
    }
}

cout << mx;



return 0;

}

m,n=map(int,input().split()) while m>0: m,n=n%m,m print(n)
