[QUOTE=GP2;550090][M]M10,443,557[/M] has been reported fully factored.[/QUOTE]I tried to get a PRP-CF-D assignment of this via the manual assignment page. PrimeNet didn't want to give it to me.

[QUOTE=ATH;550103]You are welcome to run it with your own software. PFGW takes a very long time because it can only use 1 core and because it does a lot of other tests before starting the Lucas test. Last 2 took 4.5 and 5.7 days, this would probably take 8+ days.[/QUOTE]

I took liberty to let Lifchitz [URL="http://www.primenumbers.net/prptop/prptop.php"]PRP Top site[/URL] know.
It is in position #3 now.

[c](2^10443557-1)/37289325994807 is Fermat, Lucas and Frobenius PRP! (P = 5, Q = 3, D = 13) Time : 80331.237 sec.[/c]

[QUOTE=GP2;550090][M]M10,443,557[/M] has been reported fully factored.

This would be a new record. The previous record-holder was [M]M7,313,983[/M][/QUOTE]

[M]M10,443,557[/M] was 344th.

345th is [M]M3307[/M], as reported [URL="https://www.mersenneforum.org/showthread.php?p=551249#post551249"]here[/URL] and [URL="https://www.mersenneforum.org/showthread.php?p=551258&#post551258"]here[/URL]

The cofactor was certified in factordb on July 19th.

Yay! :party:

The 346th fully-factored or probably-fully-factored Mersenne number with prime exponent (not including the Mersenne primes themselves) is M1999.

The most recent factor (49 digits) was found by Ryan Propper on September 02 and the cofactor was certified to be prime by anonymous and verfied by FactorDB.

Gelly has proved the [URL="https://primes.utm.edu/primes/page.php?id=131278"]M84,211 cofactor[/URL]. The page [url]https://www.mersenne.ca/prp.php[/url] needs to be updated.

Impressive. How long did that take?
