Write a C program to find HCF and LCM of two given numbers

#include<stdio.h>
main()
{   
    int n1,n2,num1,num2,lcm,rem;
    printf("\nEnter two numbers=");
    scanf("%d%d",&num1,&num2);
    printf("\nThe two numbers are %d and %d",num1,num2);
    if(num1>num2)
    {
        n1=num1;
        n2=num2;
    }
    else
    {
        n1=num2;
        n2=num1;
    }
    while(n2%n1!=0)
    {
        rem=n2%n1;
        n2=n1;
        n1=rem;
    }
    lcm=(num1*num2)/n1;
    printf("\nH.C.F. of %d and %d is %d",num1,num2,n1);
    printf("\nL.C.M. of %d and %d is %d",num1,num2,lcm);
}
