Question

Java

It would be nice if you use many Functions.

1. rite a method, besides main(), which will calculate the lowest common multiple (LCM) of two numbers. For example, the multiples of 4 are 4, 8, 12, 16, 20, 24 …, and the multiples of 6 are 6, 12, 18, 24 …. The LCM is 12.
2. Do NOT use any code from the Internet!
3. Here are some more examples:
   3:5 LCM is 15
   4:8 LCM is 8
   5:7 LCM is 35
4. Your method will take two parameters, and return the LCM for those numbers.
5. Demonstrate your function is working by finding the LCM for 16:20 and 13:17

Answer 1

import java.util.*;

public class FindLcm
{
   public static void main (String[] args) throws java.lang.Exception
   {
       Scanner sc=new Scanner(System.in);
       System.out.println("Enter two numbers : ");
       int n=sc.nextInt();
       int m=sc.nextInt();
       int l=LCM(n,m);
       System.out.println("Lcm of "+n+" and "+m+" is "+l);
   }
   public static int LCM(int num1,int num2)
   {
       int lcm=0,m;
       m = (num1 > num2) ? num1 : num2;
for(int i=0;i<m;i++)
   {
   if(m%num1==0 && m%num2==0)
   {
      lcm=m;
   break;
   }
   m++;
   }
   return lcm;
   }
}
