C program to find HCF and LCM of two integers.

/*WAP to find HCF and LCM of two integers.*/
#include <stdio.h>
#include <conio.h>
int main()
{
int a, b, x, y, t, gcd, lcm;
printf("Enter two integers\n");
scanf("%d%d", &x, &y);
a = x;
b = y;
while (b != 0)
{
t = b;
b = a % b;
a = t;
  }
gcd = a;
lcm = (x*y)/gcd;
printf("Greatest common divisor of %d and %d = %d\n", x, y, gcd);
printf("Least common multiple of %d and %d = %d\n", x, y, lcm);
getch();
}

Expected Output:
Enter two integers
8
12
Greatest common divisor of 8 and 12 =4
Least common multiple of 8 and 12 =24
