Submitted by Nidhi, on December 16, 2021

Problem Solution:

In this program, we will read two integer variables from the user. Then we will get the Greatest Common Divisor and Lowest Common Multiple using the gcdlcm() function.

Program/Source Code:

The source code to get the GCD and LCM using the gcdlcm() library function is given below. The given program is compiled and executed successfully.

# Ruby program to get the GCD and LCM using 
# the gcdlcm() library function

print "Enter number1: ";
num1 = gets.chomp.to_i;  

print "Enter number2: ";
num2 = gets.chomp.to_i;  

gcd,lcm = num1.gcdlcm(num2);

print "Greatest Common Divisor: ",gcd,"\n";
print "Lowest Common Multiple:  ",lcm,"\n";

Output:

Enter number1: 21
Enter number2: 14
Greatest Common Divisor: 7
Lowest Common Multiple:  42

Explanation:

In the above program, we read two integer variables from the user using gets.chomp.to_i. Then we got the Greatest Common Divisor and  Lowest Common Multiple using library function the gcdlcm() and assign the result to the gcd ,lcd variables. After that, we printed the result.
