java program to find lcm of two numbers

1public class LCMOfTwoNumbers
2{
3   public static void main(String[] args)
4   { 
5      int num1 = 85, num2 = 175, lcm;
6      lcm = (num1 > num2) ? num1 : num2;
7      while(true)
8      {
9         if(lcm % num1 == 0 && lcm % num2 == 0)
10         {
11            System.out.println("LCM of " + num1 + " and " + num2 + " is " + lcm + ".");
12            break;
13         }
14         ++lcm;
15      }
16   }
17}

1calculate lcm two numbers in java we can use GCD
2public class LCMUsingGCD 
3{
4   public static void main(String[] args) 
5   {
6      int num1 = 15, num2 = 25, gcd = 1;
7      for(int a = 1; a <= num1 && a <= num2; ++a)
8      {
9         if(num1 % a == 0 && num2 % a == 0)
10         {
11            gcd = a;
12         }
13      }
14      int lcm = (num1 * num2) / gcd;
15      System.out.println("LCM of " + num1 + " and " + num2 + " is " + lcm + ".");
16   }
