9. Program

9. Find the LCM of 3 Number ?
 
like input is 3 4 5 then output will be 60

import java.util.Scanner;
class Lcm
{ static int i=0, flag = 0;
 private static int lcm(int a, int b, int c){
  if(a==0 || b==0 || c==0 )
  {
   System.out.println("Error Message : Number must be greater then 0");
   return 0;
  }

  while( flag == 0)
  {
   i++;
   if(i%a == 0 && i%b == 0 && i%c == 0)
   {
    flag = 1;
   }
  }
  return i;
 }
 public static void main(String args[])
 {
  Scanner sc = new Scanner(System.in);
  System.out.println("Enter first Number : ");
  int x = sc.nextInt(); 
  System.out.println("Enter second Number : ");
  int y = sc.nextInt();
  System.out.println("Enter third Number : ");
  int z = sc.nextInt(); 
  System.out.println("LCM of "+x+", "+y+" & "+z+" is : "+lcm(x,y,z));
 }
}
