Yes, 1100000000003937045 is the factordb id was talking about having failed to get trial factoring. If you click "Primality" and then click "N-1" you get this. But it is easy to see that every prime up to 2557 except 19 divides this. I think it's a bug that this got into the factordb without accurate trial factoring.

There's nothing special about this number; a lot of the recent 7x digit composites had a largest prime factor of only 5 or 6 digits, so obviously some method of inserting numbers to the db doesn't do any checking at all.

[URL="http://factordb.com/stat_1.php"]This page[/URL] has a typo; "composize" should be "composite".

The [url=http://factordb.com/status.php]Status page[/url] got another one:

The point under "The database is running on" says: "Power consumpion".

Syd, what ist database's oldest (smallest id) unfactored composite?

[url]http://factordb.com/index.php?id=1000000000000001061[/url] seem a good candidate

Not for a long time, see [url=http://escatter11.fullerton.edu/nfs/numbers.html]NFS@Home[/url].

i think that the sieving will take a few more weeks/months, therefore comply with the 'oldest' composite;p

Something's broken....
 

I was looking at some of the longest sequences and ran acorss a problem with one. [URL="http://factordb.com/sequences.php?se=1&eff=2&aq=933436&action=last20&fr=0&to=100"]933436[/URL] doesn't display anything, just a blank screen (althogh it does take ~8800 quesries to do it).

I got it to "display last element" once, and it reported:[quote=factordb]Error on number 105989556098056466581697879875892687048953224897793946376047041572910440644406075202864343735423530347128160400[/quote]Searching on that [URL="http://factordb.com/index.php?id=1100000000443037764"]number[/URL] shows it as FF, but the factorization is wrong:[code]FF 111 (show) 1059895560...0<111> = 2^4 · 5^2 · 29510540564780279914245519428917891801999<41> · 1340002219...3<54> [/code]Pasting it into Dario's [URL="http://www.alpertron.com.ar/ECM.HTM"]applet[/URL] shows this factorization:[quote=Alpertron]105989556098056466581697879875892687048953224897793946376047041572910440644406075202864343735423530347128160400

[B]More Broken[/B]

Here is a simpler case that is broken

677^7-1 shows as 20 digits and fully factored

http://factorization.ath.cx/index.php?query=677^7-1

But the factorization shown is for 677-1
