least common multiple java code example

Example: Java program to find LCM of two numbers

calculate lcm two numbers in java we can use GCD
public class LCMUsingGCD 
{
   public static void main(String[] args) 
   {
      int num1 = 15, num2 = 25, gcd = 1;
      for(int a = 1; a <= num1 && a <= num2; ++a)
      {
         if(num1 % a == 0 && num2 % a == 0)
         {
            gcd = a;
         }
      }
      int lcm = (num1 * num2) / gcd;
      System.out.println("LCM of " + num1 + " and " + num2 + " is " + lcm + ".");
   }
}
