Program/Source Code:

The source code to find the LCM using the library function is given below. The given program is compiled and executed successfully.

# Ruby program to find the LCM 
# using library function

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

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

result = num1.lcm(num2);

print "Lowest Common Multiple: ",result;

Output:

Enter number1: 20
Enter number2: 15
Lowest Common Multiple: 60

Explanation:

In the above program, we read two integer variables from the user using gets.chomp.to_i. Then we got the Lowest Common Multiple using library function lcm() and assigned the LCM to the result variable. After that, we printed the result variable.
