Now we just need to workout what to do with it.

That's my thinking as well Corky. It's all well and good finding these prime numbers, but why do we need to know what they are?
I think you should have copy pasted the whole number into the article in a pop out quote if people want to see it

nice
Large prime numbers are very useful for encryption, amongst other things:

True, but this is a Mersenne prime number, not that I'm clever enough to know, or even understand, the difference between the two.
And before anyone tries explaining it to me, i read the explanation in the article but it made about much sense to me as when i tried to understand quantum physics so it's probably best to just accept that it's beyond my comprehension.

For prime numbers to work with encryption they have to be secret, not plastered on a Wikipedia page
Actually that isn't quite true, public keys use simple known primes but choose numbers that in binary have as few '1' bits as possible. That makes Mersenne primes worst case, for each set bit you need to perform an operation. You usually use 2^16+1 as a public prime.
Wrong wording here, Mike. "X to the power of two" is X^2. Mersenne numbers are (2^X)-1. You'd have to say "the prime number is one less than two to the power of another number".the prime number is one less than another number to the power of two
