Program to find LCM (Lowest Common multiple) of given two numbers in C

This Program is used to find LCM (Lowest Common multiple) of given two numbers in C langauge.

int GCD(int n, int m)
{

    int temp;
    while( m > 0)
{
        temp = n;
        n = m;
        m = temp % m;
    }
    return n;
}

int LCM(int n, int m) {
    int product = n*m;
    int gcd = GCD(n,m);
    int lcm = product/gcd;
    return lcm;
}
int main()
{
    int n, m;
    scanf("%d%d",&n,&m);
    printf("%d\n",LCM(n,m));
    return 0;
}
