程序代码：

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int n, m;
    int max = 0;
    int temp = 0;
    
    printf("请输入两个整数:");
    scanf("%d %d", &n, &m);
    
    int x = n;
    int y = m;
    
    while( m > 0 )
    {
        temp = m % n;
        n = m;
        m = temp;
    }
    printf("GCD = %d\n", n);
    
    if( x > y )
    { max = x; }
    else
    { max = y; }
    
    while( max < x * y )
    {
        if( max % x == 0 && max % y == 0)
        { break;}
        else
        { max++; }    
    }
    printf("LCM = %d\n", max);
    
    system("pause");
    return 0;
}
