Write a C program to find HCF and LCM.

#include <stdio.h>

 void 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);

}
