Hi there in this article I would like to share with you a program that I wrote in PHP to compute for the Greatest Common Divisor. What does our program will do is to ask the user to give two numbers and then it will compute it greatest common divisor equivalent.
Add me at Facebook my address is jakerpomperada@gmail.com and jakerpomperada@yahoo.com.
My mobile number here in the Philippines is 09173084360.
