C Program to find Hcf and Lcm Of numbers

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