Ruby program to calculate the Lowest Common Multiple

Program/Source Code:

The source code to calculate the Lowest Common Multiple is given below. The given program is compiled and executed successfully.

# Ruby program to calculate the 
# Lowest Common Multiple

num1=0
num2=0
rem=0
lcm=0
x=0
y=0

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

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

if (num1 > num2) 
    x = num1;
    y = num2;
else 
    x = num2;
    y = num1;
end

rem = x % y;

while (rem != 0) 
    x = y;
    y = rem;
    rem = x % y;
end

lcm = num1 * num2 / y;

print "Lowest Common Multiple is: ",lcm;

Output:

Enter number1: 125
Enter number2: 10
Lowest Common Multiple is: 250

Explanation:

In the above program, we created six variables num1, num2, rem, lcm , x, y initialized with 0. Then we read values num1 and num2 from the user. After that, we found the Lowest Common Multiple and printed the result.
