bhargava_v Posted February 6, 2013 Report Posted February 6, 2013 [color=#000000][font=arial, helvetica, sans-serif][size=3] The [url="http://www.mersenne.org/various/57885161.htm"]biggest prime number yet[/url] has been discovered.[/size][/font][/color][color=#000000][font=arial, helvetica, sans-serif][size=3] It is indeed massive, [url="http://www.isthe.com/chongo/tech/math/digit/m57885161/prime-c.html"]more than 17 million digits long[/url]. [url="http://www.isthe.com/chongo/tech/math/digit/m57885161/huge-prime-c.html"]A text file[/url] of the entire number contains more than 22 megabytes of information.[/size][/font][/color][color=#000000][font=arial, helvetica, sans-serif][size=3] For those who have been out of school for a while, let's review: A prime number is a positive integer that cannot be divided evenly by any number except itself and 1. The first 10 prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29.[/size][/font][/color][color=#000000][font=arial, helvetica, sans-serif][size=3] There is no clear pattern in these numbers, nor is there an easy formula to calculate the 11th prime number (31). And, as proven by the great mathematician Euclid, around 300 B.C., there are an [url="http://primes.utm.edu/notes/proofs/infinite/euclids.html"]infinite number of primes[/url].[/size][/font][/color][color=#000000][font=arial, helvetica, sans-serif][size=3] That means there are unfathomably large numbers that are prime. The newest find is 2 to the power of 57,885,161 minus 1. That means 2, multiplied by 2 more than 57 million times, minus 1. Don't try this on any ordinary calculator.[/size][/font][/color][color=#000000][font=arial, helvetica, sans-serif][size=3] The lucky number-hunter who came upon it is [url="http://www.math-cs.ucmo.edu/~curtisc/primes.html"]Curtis Cooper[/url] of the [url="http://www.mersenne.org/"]Great Internet Mersenne Prime Search (GIMPS)[/url], a collaborative project involving thousands of volunteers who sift through numbers in search of primes.[/size][/font][/color] [color=#000000][font=arial, helvetica, sans-serif][size=3] [img]http://i2.cdn.turner.com/cnn/dam/assets/130206120304-prime-number-story-top.jpg[/img][/size][/font][/color]
Spartan Posted February 6, 2013 Report Posted February 6, 2013 naak okati ardham kaadu.....what will they do after finding the largest prime number.. are they gaugin the computing power to find out.....or planning to use that prime number... if they are gauging the computing power of that engine..there are many better ways to do that I feel..
