He currently is a professor at the University of Central Missouri, in the Department of Mathematics and Computer Science. == GIMPS == Using software from the GIMPS project, Cooper and Steven Boone found the 43rd known Mersenne prime on their 700 PC cluster on December 15, 2005. The prime, 230402457 − 1, is 9,152,052 digits long and is the ninth Mersenne prime for GIMPS.〔.〕 Cooper and Boone became the first GIMPS contributors to find two primes when they also found the 44th known Mersenne prime, 232582657 − 1, which has 9,808,358 digits (or M32582657 for short). This prime was discovered on September 4, 2006 using a PC cluster of over 850 machines. This is the tenth Mersenne prime for GIMPS.〔.〕 On January 25, 2013, Cooper found his third Mersenne prime, which is 257,885,161 − 1. It is also the largest known prime number as of January 2014.〔(【引用サイトリンク】title=GIMPS Project Discovers Largest Known Prime Number, 257,885,161-1 )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Curtis Cooper (mathematician)」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
