Submitted by Nidhi, on December 25, 2021

Problem Solution:

In this program, we will read two integer numbers from the user and find the LCM of input numbers using recursion.

Program/Source Code:

The source code to find the LCM of two given numbers using recursion is given below. The given program is compiled and executed successfully.

# Ruby program to find the LCM of 
# two given numbers using recursion

def LCM(a, b, res)
    if (res % a == 0 && res % b == 0)
        return res;
    else
        LCM(a, b,res + 1);
    end
end

print "Enter number1: ";
number1 = gets.chomp.to_i;  

print "Enter number2: ";
number2 = gets.chomp.to_i;  

result = LCM(number1, number2,1);

print "LCM is: ",result;

Output:

Enter number1: 45
Enter number2: 75
LCM is: 225

Explanation:

In the above program, we read two integer numbers from the user. Then we found the LCM of input numbers using recursive function LCM(). Then we printed the result.
