As for the next prime number record waiting to be crunched, the EFF will award $150,000 to the first person or group who discovers a prime with at least 100 million digits and $250,000 for a prime with at least a billion digits.

You can download the GIMPS distributed computing software and join the hunt here.

A Mersenne number is a number that is one less than the power of two, or M<SUB>n</SUB> = 2<SUP>n</SUP> – 1. The first few are 1, 3, 7, 15, 31, 63, and so forth (but add up quickly, as numbers tend to do). Mersenne primes are Mersenne numbers that are also prime numbers, meaning they are divisible only by 1 and itself.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.theregister.co.uk/2009/10/14/45th_mersenne_prime_verified_revelaed/"><P>The winning number in shorthand is 2<SUP>43,112,609</SUP>-1. Written out, it spans over 12-million decimal digits (nearly 13 million). Down one notch is the 44th Mersenne prime (2<SUP>32,582,657</SUP>-1) at a very respectable 9,808,358 digits long.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.theregister.co.uk/2009/10/14/45th_mersenne_prime_verified_revelaed/"><div align="center"><img src="http://content8.clipmarks.com/blog_cache/www.theregister.co.uk/img/6491E837-1181-4C67-80B9-01593ED4C47A" alt="" /></div></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/C6AFCB6A-1FA8-454E-A067-B131C9DB2465/blog/" title="blog or email this clip"><img src="http://content9.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
