[QUOTE=GeoffreyY;454860]factordb still thinks that these two are 82 digit composites:
9699691 (id 1100000000912669113)
223092871 (id 1100000000912669114)[/QUOTE]



Incorrect use of ##

1+8##
1+9##

Why am I getting the factorization of a 64-digit number instead of a 61-digit number?
 

Why does the DB say that [URL="http://www.factordb.com/index.php?query=2*3^18*19^18*363889*109912203092239643840221"]this number[/URL] is 2*3[sup]24[/sup]*19[sup]18[/sup]*363889*109912203092239643840221 instead of 2*3[sup]18[/sup]*19[sup]18[/sup]*363889*109912203092239643840221? I checked in Pari/gp, and it says this:

[CODE](18:11) gp > factor(3226950014783883023598007090793710151258504258637092076077562)
%1 =
[ 2 1]

[ 3 18]

[ 19 18]

[ 363889 1]

[109912203092239643840221 1]

(18:11) gp > 2*3^18*19^18*363889*109912203092239643840221
%2 = 3226950014783883023598007090793710151258504258637092076077562
(18:17) gp >[/CODE]Somehow, the db messed up on the power of 3, and reports the factorization of [URL="http://www.factordb.com/index.php?id=1100000000915649799"]this[/URL] number instead.

Problem with (10^79-181)%(10^79-1)/9
 

Hi all.
There is a problem with [url]http://www.factordb.com/index.php?id=1100000000900935563[/url].
It's proven prime, but it's still shown as composite at [url]http://www.factordb.com/listtype.php?t=3[/url], which gives some inconveniencies during automatic factorization.
I hope the factordb's admins can manually set this number prime.

I'm also having problems with 2*3[sup]14[/sup]*19[sup]18[/sup]*363889*109912203092239643840221, 2*3[sup]16[/sup]*19[sup]18[/sup]*363889*109912203092239643840221, and 2*3[sup]19[/sup]*19[sup]18[/sup]*363889*109912203092239643840221. They also have the wrong factorization.

I've just sent Marcus an email listing the various problems I can see in factordb (the ones on the first page of composite numbers and the composite in the list of PRPs). I'll let you know if he replies with anything interesting.

Chris

I've had a reply from Markus saying he has very little time at the moment, but will look at it soon.

Chris

Two more problems:

The distribution of probable primes shows one of 22 digits. But the list of probable primes at [url]http://factordb.com/listtype.php?t=1[/url] doesn't show anything (unless you set min digits to something larger than 22). This is probably why the status page doesn't show the smallest PRP now.

The list of composite numbers at [url]http://factordb.com/listtype.php?t=3[/url] has a similar issues at 22 and 30 digits (and possibly some more between those ranges).

Chris

reporting factors problem
 

I am reporting factor to composite.
Factor is known from 2014, but 'source' number is still marked as 'C'.
After reporting factor db shows attached screen.

What on Earth is wrong with these number entries?!
 

What's going on here?!

x=14, 16, 18, and 19 are showing the wrong factorizations. It's the same problem that's going on [URL="http://www.mersenneforum.org/showpost.php?p=455056&postcount=167"]here[/URL]. Please fix it! It's been like that since St. Patrick's Day, and it's getting to be really annoying! Also the DB workers are stuck on [URL="http://www.factordb.com/listtype.php?t=3&mindig=1&perpage=743&start=0"]743 numbers <1 quintillion[/URL] that just won't go from C to FF, even though all the factors are already there, resulting in larger composites not getting factored.
