- I was messing around with a homebrew (and offbeat) factoring method

which popped up a couple of factors for 2^2049-1. I've checked

factoredM.txt and they aren't in there so I was wondering are they

known and if not where to submit them.

The two factors are:

43483649911260969479572395841704886129976814428344266240209592218046281

2746769

and

67513796971703570854592232797421324116119881147340327278928245456644619

(683 divides 2049).

In lowM.txt at M( 2049 ).

My lowM.txt is from February 2005 but I assume the factor is still there.

factoredM.txt is only for completely factored Mersennes.

I think it omits the largest factor.

By the way, you can search numbers in Google which knows both factors.
