C# Sharp For Loop: Exercise-44 with Solution

Write a program in C# Sharp to find LCM of any two numbers using HCF.

C# Sharp: Determine the LCM of two numbers using HCF

Sample Solution:-

C# Sharp Code:

using System;  
public class Exercise44
{  
    public static void Main()  
{  
    int i, n1, n2, j, hcf=1,lcm;  
	Console.Write("\n\n");
    Console.Write("Determine the LCM of two numbers using HCF:\n");
    Console.Write("---------------------------------------------");
    Console.Write("\n\n");	


    Console.Write("Input 1st number for LCM: ");  
    n1 = Convert.ToInt32(Console.ReadLine());	
    Console.Write("Input 2nd number for LCM: ");  
    n2 = Convert.ToInt32(Console.ReadLine());	
  
    j = (n1<n2) ? n1 : n2;  
  
    for(i=1; i<=j; i++)  
    {  

        if(n1%i==0 && n2%i==0)  
        {  
            hcf = i;  
        }  
    }  
/* We know  the multiplication of HCF and LCM is equivalant
to the multiplication of these two numbers.*/
    lcm=(n1*n2)/hcf;
  
    Console.Write("\nThe LCM of {0} and {1} is : {2}\n\n", n1, n2, lcm);  
  }
}

Sample Output:

Determine the LCM of two numbers using HCF:                                                                 
---------------------------------------------                                                               
Input 1st number for LCM: 8                                                                                 
Input 2nd number for LCM: 12                                                                                
The LCM of 8 and 12 is : 24
