C program to find hcf and lcm

#include <stdio.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);
 
  return 0;
