Question

Write program to print all common multiples of two numbers up to the product of the numbers.

Answer 1

import java.util.*;
class clCommon
{
    void main()
    {
       Scanner sc = new Scanner(System.in);
       int n1, n2;
       System.out.print("Enter number1 : ");
       n1 = sc.nextInt();
       System.out.print("Enter number2 : ");
       n2 = sc.nextInt();
       System.out.println("Common Multiples of " +n1 + " & " + n2 + "are : ");
       for(int m = Math.max(n1, n2); m<= n1 * n2; m++)
       {
           if(m%n1=0 && m%n2=0)
           {
             System.out.print("" + m);
           }
       }
    }
}

Output:

Enter number 1 : 9 

Enter number 2 : 15 

Common Multiples of 9 & 15 are :

45 90 135
