Mo. Researchers Find Largest Prime Number


By GARANCE BURKE
Associated Press Writer

KANSAS CITY, Mo.

Researchers at a Missouri university have identified the largest known prime number, officials said Tuesday.

The team at Central Missouri State University, led by associate dean Steven Boone and mathematics professor Curtis Cooper, found it in mid- December after programming 700 computers years ago.

A prime number is a positive number divisible by only itself and 1 _ 2, 3, 5, 7 and so on.

The number that the team found is 9.1 million digits long. It is a Mersenne prime known as M30402457 _ that's 2 to the 30,402,457th power minus 1.

Mersenne primes are a special category expressed as 2 to the "p" power minus 1, in which "p" also is a prime number.

"We're super excited," said Boone, a chemistry professor. "We've been looking for such a number for a long time."

The discovery is affiliated with the Great Internet Mersenne Prime Search, a global contest using volunteers who run software that searches for the largest Mersenne prime.

At last humanity is saved!!!!

Seriously, besides the sheer nerdy joy in finding a new prime number, what's the point?

Chuck Norris knew this 14 years ago.

I think that these numbers are valuable in the cryptologic sector of the military.

Since encryption technology often employs incredibly large prime numbers, this could means that new encryption techniques could come from this that will be even harder to crack.

+2^30,402,457 minus 1

(it's the new +1 for arfcom)

Gee... I sure hope that progam was paid for with my tax dollars!

Maybe so, but the "answer" is STILL 42.

I believe that is the code my cell phone bill is written in.

Well, I for one will sleep better tonight. I was wondering when they were going to solve this.

I have that formula on my schmeckel. Funny thing is I thought it was a birthmark all of these years.

CMSU, huh? I would've thought it would've been UMR.

You just wasted post 556!

I hope you do post 762 better.

Actually 2^87-1 days ago, but who's counting.

And now the search is on for the question.... to the answer.

Haven't seen the movie, just started reading the book.

2^30,402,457 - 1 = 2^30,402,457 - .9bar

The entire series was great! And as you have not finished, I will not reveal the "question".

If they rely on me to type that prime number their data is really safe as I cant type a series of words in any given post without a typo or spelling error...

That is just insane and well into the category of WHO CARES?
