Related: About this forumNew largest prime number found
From phys.org:
(Phys.org)A team at the University of Central Missouri, headed by Curtis Cooper has announced, via press release from the Messene organization, that they have found the largest prime number everit is 274,207,281 1, it has over 22 million digits. The new record has broken the old record by approximately 5 million digits.
Cooper and his team are part of the Great Internet Messene Prime Search (GIMPS) collaboration, which as its name suggests, is an effort by a lot of volunteers to find ever larger prime numbersor, more specifically, a particular class of prime numbers that are called Mersenne, where it is one less than a power of two. Not surprisingly, Cooper and his team also held the old record, they have actually broken the record four times. He has told the press that he was notified by an email sent by the software running on a PC that the prime number had been found. The find came after a month of number crunching on a single Intel based PC. Interestingly, the PC tried to notify Cooper and his team about the find back in September of last year, but a glitch prevented it from being sent. It was only during a maintenance cycle that the message reporting the number prime number found, was sent. The official discovery date is January 7th.

Here's an interesting tidbit:
Earlier this month, GIMPS' prime95 software and members of a German computing community uncovered a flaw in Intel's latest Skylake CPUs.

the largest known Mersenne prime was 211213-1. That's a huge leap in just 50 years.
And it's Mersenne prime, not Messene prime.
(I've said it before and I'll say it again, the news media can't seem to get anything right.)
