Default Ever wonder the worlds largest perfect number?

Well here it is
http://calendarhome.com/prime/perfect4.html

A perfect number is when the divisors (not including the number itself) are added together and it equals the number

Only 47 exist. Wonder how the on in the link was found haha

Its hard going through over a million digits. That must have taken years to find

Awesome. I love number theory. I'm terrible at any math beyond algebra, but it's clear that patterns exist in numbers, bizarre patterns that are way cool as hell.

I think theorists are still trying to find a proof that says there's an infinite number of perfect numbers, but they can't come up with such a proof yet?

There's a really nice book that talks about the history behind Fermat's Last Theorem. The book is called "Fermat's Enigma", and it's very easy to read for anyone with no more than a basic understanding of algebra.

Well if there are an infinite amount of numbers then theres an infinite amount of perfect numbers theyre just spaced really far apart. Its just like prime numbers: at first theyre all close together then really far apart

Heh. If mathematical proof's were that easy... but they aren't.

Oh wow, very cool, I'm watching some now. They have a great video about 6174. That's a great trick, you can use that at parties to really freak people out.

6174 - Numberphile - YouTube

Thanks for the tip!

Well, what is the square root of 69, then?

I just reserved this book from the public library. I only know the broad strokes of how it was proven from a talk Malcolm Gladwell gave at The New Yorker Conference a couple of year's ago. There, Gladwell used the example of Wiles to discuss the role of collaboration in contemporary problem solving. Can't wait to read the book! Thanks for the recommendation!

The Yankees v. Mets Subway Series game has been on pause for the last thirty minutes because of you! Thanks for the suggestion!
