Date: 9/8/96 at 9:41:53 From: Doctor Sarah Subject: Re: Largest Prime Number Hi Trisha - Chris Caldwell's Web page, THE PRIME PAGE (the prime source for information about prime numbers), will tell you all about primes: http://www.utm.edu/research/primes/index.html Chris is also the author of a page called The Largest Known Primes with a nice "Introduction (What are primes? Who cares?)" at: http://www.utm.edu/research/primes/largest.html This was the latest from The Largest Known Primes page as of Sept. 3, 1996: "On 3 September 1996, Cray Research (a subsidiary of Silicon Graphics), announced that David Slowinski and Paul Gage have found a new record prime: 2^1257787-1. The proof of this 378,632 digit number's primality (using the traditional Lucas-Lehmer test) took about 6 hours on one CPU of a CRAY T94 super computer. George Woltman, Richard Crandall and others independently verified the primality." -Doctor Sarah, The Math Forum Check out our web site! http://mathforum.org/dr.math/
