Program/Source Code:

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

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

def calculateGCD(a, b)
    while (a != b)
        if a > b
            return calculateGCD(a - b, b);
        else
            return calculateGCD(a, b - a);
        end
    end
    
    return a;
end

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

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

result = calculateGCD(number1, number2);

print "GCD is: ",result;

Output:

Enter number1: 45
Enter number2: 75
GCD is: 15

Explanation:

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