# The Biggest Prime Number, So FarNPR.

The largest known prime has almost always been a Mersenne prime. Why Mersennes? Because the way the largest numbers N are proven prime is based on the factorizations of either N1 or N-1. For Mersennes the factorization of N1 is as trivial as possible--a power of two!

The largest known prime today is the 24,862,048 digit Mersenne prime 2 82589933-1 found in December 2018, but how big have the "largest known primes" been historically? Historically, how have these primes been found? May 20, 2013 · The largest prime number discovered so far is 2 raised to the 57,885,161st power minus 1, or 2 57,885,161- 1. It is 17,425,170 digits long. It was discovered by University of Central Missouri mathematician Curtis Cooper as part of a giant network of volunteer computers devoted to finding primes. Jan 09, 2017 · I’m not a mathematician, so I don’t know how their process differs from that of finding Mersenne primes, but it currently as of January 10, 2017 ranks 7th on the list of known primes. It has 9,383,761 decimal digits, making it the only non-Mersenne prime with over 4 million.

To power through these gigantic numbers, scientists use the Great Internet Mersenne Primes Search GIMPS, which uses the computing power of thousands of Internet users to search for the elusive prime numbers. The largest known prime number, 2^57,885,161 – 1, has over 17 million digits and was discovered this year. December 21, 2018 — The Great Internet Mersenne Prime Search GIMPS has discovered the largest known prime number, 2 82,589,933-1, having 24,862,048 digits.

Jan 22, 2016 · The previous largest was 2 ⁵⁷,⁸⁸⁵,¹⁶¹ − 1, which has a mere 17 million or so digits. This is the 15th prime number found by the Great Internet Mersenne Prime Search, or Gimps, for. This means that the largest known prime numbers are important in a way that, say, a googol - which is ultimately just a bunch of 2's and 5's multiplied together - really isn't. So far, so good. Apr 26, 2010 · What is the largest prime number so far?

Jan 20, 2016 · In reality, there's no such thing as the highest prime number, seeing as there's an infinite amount of them. But the quest to find increasingly big ones remains a big deal - so much so that Curtis Cooper, a mathematician at the University of Central Missouri, won US\$100,000 for discovering the previous highest prime back in January 2013.
