GIMPS has discovered a new largest known prime number: 282589933-1 (24,862,048 digits)

Samuel Yates began, and this site continues, a database of the largest known primes. Primes in that database are assigned a proof-code to show who should be credited with the discovery as well as what programs and projects they used. (Discoverers have one prover-entry, but may have many proof-codes because they use a variety of programs...) This page provides data on L1505, one of those codes.

Code name (*):L1505
Persons (*):1 (counting humans only)
Projects (*):1 (counting projects only)
Display (HTML):Watanabe, PSieve, Srsieve, PrimeGrid, LLR
Number of primes:total 27
