第一次用函数……  内存不能为READ的问题。求大神教

# include <stdio.h>
void mm(int a,int b,int *l,int *g);
int main()
{
    int n;
    int a,b;
    int i = 1;
    scanf("%d",&n);
    
    while(n--)
    {
        scanf("%d %d",&a,&b);
        int lcm,gcf;
        mm(a,b,&lcm,&gcf);
        printf("%d %d %d",i++,b,a);
    }
    return 0;
}

{
    if(a == b)
    {

        *g = a;
    }
    else if(a > b)
    {
