Humungous Prime Number Discovered AP
posted: 6 HOURS 9 MINUTES AGOcomments: 64filed under: Science NewsPrintShareText SizeAAALOS ANGELES (Sept. 27) -
Mathematicians at UCLA have discovered a 13-million-digit prime number, a long-sought milestone that makes them eligible for a $100,000 prize.
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.
"We're delighted," said UCLA's Edson Smith, the leader of the effort. "Now we're looking for the next one, despite the odds."
It's the eighth Mersenne prime discovered at UCLA.
Primes are numbers like three, seven and 11 that are divisible by only two whole positive numbers: themselves and one.
I've wondered this for years.
Why do we care?
Is there any useful purpose for knowing prime numbers?
Would someone kindly answer either of these questions please.

They have to do something with all that tuition money they receive from students. :D

Finding immense unusable prime numbers is what math nerds have wet dreams over

Prime numbers are used in security codes. I had a math professor explain how they were used, but I have since forgotten the details.

Mersenne? what is mersenne?

Mersenne? what is mersenne?
Mersenne numbers consist of all 1s in base-2, and are therefore binary repunits (a base-10 repunit is a number like 11, 111, or 1111 - numbers that contains only the digit 1).
The first few Mersenne numbers are 1, 3, 7, 15, 31, 63, 127, 255...

I got an even more puzzling question! Who would care enough to off a $100,000 prize for this little gem of data? :uhoh

13-million-digit prime number for only $100,000! What a bargain!
I want one!

Yeah, and I was thinking, how much time and money did they spend trying to figure out this number? I know 100g's isn't going to cover it.

A more succinct definition: In mathematics, a Mersenne number is a positive integer that is one less than a power of two.

The group found the task made them forget how to Rip and paste properly. A secondary investigation discovered they carpeted their garage ceiling.
Why do we care?
