C Program to find LCM lowest(least) Common Multiples & GCD Greatest Common Divisor

#include<stdio.h>

int GCD(int a,int b)
{
    int c;
    while(b > 0)
    {
        c = a%b;
        a = b;  b = c;
    }
    return a;
}
int main()
{
    int i,a,b,LCM;
    while(scanf("%d%d",&a,&b)==2)
    {
        LCM = (a*b) / GCD(a,b);
        printf("%d\n",LCM);
    }
    return 0;
}

Input:
501 36
14 6
24 12

Output:
