Least Common Multiple (LCM) Number Finder in PHP

In this article I would like to share with you a basic math problem in finding least common multiple numbers using PHP as my programming language. Least Common Multiple numbers it refers to the smallest nonzero number that is a multiple of two or more numbers.

I hope you will find my work useful in learning how to write a program in PHP as your programming language.

If you have some questions please send me an email at jakerpomperada@yahoo.com and jakerpomperada@gmail.com.

My work is based on the work of TutsForWeb the website can be located in this following link http://tutsforweb.blogspot.com/2012/05/auto-complete-text-box-with-php-jquery.html i found their work useful in web design and development so that's why I used it in my example in this article.

What is program will do is to ask the user to type the name of a programming language in the text field is the letter or word match it will display on the screen it makes searching of records much easier compared with the traditional way. I'm using the Jquery library autocomplete to perfrom the task of autocomplete. I hope you will find my work useful in your building of web based application using PHP as your main progrmming language.

Power of a Number in PHP

In this program will ask the user to enter the base and exponent of a number a number and then it will compute for the power of the number given by the user. Example if our user will give 5 as its base and the exponent is 3 the computed result is 125. As simple as 5 * 5 *5 we just multiply 5 by 3 time.
