For those of us who don't want to read it, the new number is a Mersenne Prime, which can be written as (2^P) -1, where P is also a prime number. P, in this instance, is 43,112,609.

It's UCLA's 8th Mersenne Prime and is likely to win them a nice chunk of change - $100K.


Am I the only one who thinks this is so cool? I'm a giant nerd...I love mathematics.

Nope, I think it's cool too!  I'm a maths teacher and I will be telling my students about this on Monday....

In the common numbers we use everyday you have 1,3 5 and so on for primes, there is quite a few up to 10, from 11-20 not so many...21-30 even less....and they become rarer as the number line lenghtens....as in pi there appears to be no repeating pattern, other than you can take what is not prime by half and see if there is a divisor in there. 

A number with thirteen million digits being prime is probably not so useful to us, in terms of figuring out the checkbook, but it may be gaining currency, we may need it to figure out prime rate for lending on our national debt.

The most fascinating thing about primes is that there is no discernable pattern that we can find YET that will help us predict where the next one will be.  As a mathematician and physicist by training, we are taught that there are patterns out there to help solve problems, if you look hard enough and long enough. 

To find prime numbers though, the challenge is still there and the pattern is still a mystery.  Primes tend to be found now by 'trial and improvement' - use the biggest, most powerful computer you can, get it to start analysing a number series to see if a number has only two distinct and different factors.  If not, move on to the next number.  Time-consuming, tedious in the extreme - but how exciting when all of a sudden a prime pops out!

Errrmmmm...does anyone else think I need to get out more??

Get up.

Try to own a physicist.
Fail.

I have yet to find the pattern in there, but if I can just reduce the background noise in this equation I am sure it is staring me in the face.

I was sort of imagining some sort of collaboration, here.

Had they reached out as far as 13 when you were hitting the books, hunk?

Though there is an infinite number of primes because numbers are infinite, there are some interesting anomalies that I believe combined with anomalies, yet to be discovered, will show a pattern in order to predict other prime numbers. I am actively seeking such a formula, though my need to bring in an income holds this as only a hobby. People often ask me how I relax. This would be a typical example.

Here are the first 1000 of 455042512 known primes including the 46th Mersenne Prime the OP has posted.
