再次提醒注意代码书写风格！

#include <stdio.h>

int main (int argc, const char * argv[]) {
    
    int a, b, i, t;
    
    scanf("%d%d", &a, &b);
    
    if (a < b) {
        t = a;
        a = b;
        b = t;
    }
    
    for(i = 2; i <= b; i++)
        if(a % i == 0 && b % i == 0)
            printf("%d\t", i);
    
    return 0;
