New Mersenne Prime Number Discovered: Its 13 Million Digits Long!

UCLA mathematician Edson Smith and colleagues have found a really, really large prime number: it's 13 million digits long!

The group found the 46th known Mersenne prime last month on a network of 75 computers running Windows XP. The number was verified by a different computer system running a different algorithm. [...]

Mersenne primes — named for their discoverer, 17th-century French mathematician Marin Mersenne — are expressed as 2P-1, or two to the power of "P" minus one. P is itself a prime number. For the new prime, P is 43,112,609.

Thousands of people around the world have been participating in the Great Internet Mersenne Prime Search, or GIMPS, a cooperative system in which underused computing power is harnessed to perform the calculations needed to find and verify Mersenne primes.

To visualize how large the prime number 243,112,609 - 1 really is, if you print out the number at 75 digits per line and 50 lines per page, it would be almost 3,500 pages long!

That's a very big number. Like that's too big to describe the amount of anything in the universe. Like uh, helium atoms. I think that's the most numerous thing there is, I can't remember.

I just discovered the largest number that ever did be discovered:


I call it a Bazooglenoodlebooglekitnkaboodleplex

Alert the media! Update Wikipedia! Oh, and I have many more discoveries to come. Nine super computers in my basement are working full time to keep multiplying that little superscript.

Aaarghh! Ok, well, just open your souls and try and imagine the glorious new number in the previous comment as if the brown-shirted commie-nazi islamo-fascists at Neatorama actually allowed the superscript tag.

Ideed. What good is it? For the sake of arguement lets assume it is the largest possible Prime Number. What in your humble opinion does it represent; the number of possible Parallel Universes, Infinity, God?
