Least Common Multiple (LCM) Solver in Java

This sample program that I wrote in Java programming language will ask the user to enter two numbers and then our program will compute and determine the least common multiple or LCM of the two numbers being provided by our user.

Feel free to use my code in your programming projects at school or work.  If you have some questions please send me an email at jakerpomperada@gmail.com and jakerpomperada@yahoo.com.

Thank you very much and Happy Programming.
