C# Sharp Exercises: Find the LCM and GCD of two numbers
C# Sharp Recursion: Exercise-12 with Solution
Write a program in C# Sharp to find the LCM and GCD of two numbers using recursion.
Pictorial Presentation:
Sample Solution:
C# Sharp Code:
using System;
using System.Text;
class RecExercise12
{
public static void Main()
{
long num1, num2, hcf, lcm;
Console.WriteLine("\n\n Recursion : Find the LCM and GCD of two numbers :");
Console.WriteLine("------------------------------------------------------");
Console.Write(" Input the first number : ");
num1 = Convert.ToInt64(Console.ReadLine());
Console.Write(" Input the second number : ");
num2 = Convert.ToInt64(Console.ReadLine());
hcf = gcd(num1, num2);
lcm = (num1 * num2) / hcf;
Console.WriteLine("\n The GCD of {0} and {1} = {2} ", num1, num2, hcf);
Console.WriteLine(" The LCM of {0} and {1} = {2}\n", num1, num2, lcm);
}
static long gcd(long n1, long n2)
{
if (n2 == 0)
{
return n1;
}
else
{
return gcd(n2, n1 % n2);
}
}
}
Sample Output:
Recursion : Find the LCM and GCD of two numbers : ------------------------------------------------------ Input the first number : 2 Input the second number : 5 The GCD of 2 and 5 = 1 The LCM of 2 and 5 = 10
