The mysterious number 495

There are certain numbers that have certain characteristics.   Until now, many of these numbers become source of fascinations of mathematicians and non-mathematicians alike. Many mathematicians have spent their entire lives solving the mysteries of some numbers.  In this post, we are going to talk about the mysterious number 495.
