c program to find hcf and lcm of two numbers

program:

#include<stdio.h>
int main()
{

    int a, b, i, lcm, hcf;
    printf("enter a:\n");
    scanf("%d",&a);
    printf("enter b:\n");
    scanf("%d",&b);
    for(i=1; i<=a && i<=b;i++)
    {
        if(a%i==0 && b%i==0)
        {
            hcf=i;
        }
    }
            lcm= (a*b)/hcf;
            printf("hcf of number is:%d", hcf);
            printf("\nlcm of number is:%d", lcm);
            return 0;
}

output:
