New Possible Record Prime Number Found

An anonymous reader writes "The Great Internet Mersenne Prime Search (GIMPS), a distributed computing project, has probably found a new record prime number. Two verification runs have started; no errors were found in the initial calculation. The number of primes found lately, four in just over two years, is higher than previously expected. This prime is just under 10 million digits, which means that one of the participants in the project makes a good chance to obtain his or her part of the EFF prize of $100,000 for the first prime of over 10 million digits in the coming months. In 2000, one of the Gimps participants collected the $50,000 reward offered."

      Ah, but... a number of ten million digits? That has to take up ~ 10MB of disk space. And now the link's been posted to /., where every lunatic is now clicking on it and thinking that by some bizarre geek savant superpower they're going to somehow look at it and go 'yup, that's prime all right' or something...

      No wonder the server's a smoking crater now :)

      Indeed. The test performed to check that a Mersenne number is prime consists of repeated squaring, followed by the addition of an offset, using modular arithmetic. The number of iterations of the algorithm is equal to the value of the exponent of 2. If the final result is zero, the number is prime.

      This only works due to the Mersenne prime being one less than a number with many known factors.
