This post is about perfect numbers which is a very interesting concept in number theory.

According to bible God created everything including man in six days.

"And God saw every thing that he had made, and, behold, it was

very good. And the evening and the morning were the sixth day." (genesis 1:31 (KJV) )

But why he took six days for doing that??? He could have done all these in a fraction of a second right???

The reason is that six is the smallest perfect number.

By definition perfect numbers are those numbers that are equal to the sum of it's distinct proper factors.

for example 6= 1+2+3

the next perfect number is 28 =1+2+4+7+14

the third one is 496 and the fourth being 8128

All the known perfect numbers are even. But it is not yet proved that odd perfect numbers does not exist.

There is one theorem on even perfect numbers ie.

If (2^n -1 ) is prime, then (2^n -1 )* ( 2^ (n-1)) is a perfect number.
