Lcm of 2 numbers in c

/*
Using While loop

The following code assigns to the variable ‘max’ the number that’s the largest between num1 and num2.
*/
res = (x > y) ? x : y;

/* Code */
#include <stdio.h>
int main() {
  int x, y, res;
  printf("Enter two positive integers: ");
  scanf("%d %d", &x, &y);
  res = (x > y) ? x : y;
  while (1) {
      if (res % x == 0 && res % y == 0) {
          printf("The LCM obtained from %d and %d is %d.", x, y, res);
          break;
      }
      ++res;
  }
  return 0;
}

/* Output
Enter two positive integers: 7
35
The LCM obtained from 7 and 35 is 35.
*/



/*
Function

The same algorithm is followed for the while loop as in the lcm program in c using while, except this time, we have a function call as:
*/
lcm = findLCM(x, y);

/* Code */

#include <stdio.h> 
int findLCM(int x, int y, int res);
int main()
{
 int x, y, res;
 printf (" \n Enter two positive integers: ");
 scanf ("%d %d", &x, &y);
 res = (x > y) ? x : y;
 int lcm=findLCM(x,y,res);
 printf ( " \n The LCM obtained from %d and %d is %d. ", x, y, res);
 return 0;
}
int findLCM ( int x, int y, int res)
{ 
  while (1) {
     if (res % x == 0 && res % y == 0) {
         return res;
         break;
     }
     else{++res;}
    
 }
}


/* Output */
Enter two positive integers: 7
35
The LCM obtained from 7 and 35 is 35.
