Again "dividing" the C227 from RSA-2048 and next factorizing a little. Continuing doing the same, the PRP384 has the same P7 factor when again dividing from RSA-2048 and factorizing. Before having a cup of coffee, the thing I should not be doing is backtracking myself. The C227 should better be multlplied by the larger RSA-1024 and next take the square root of the result. Next continue with the factorizing. At least this is the way I choose to be doing it. If there could be secrets around because of this, where will these eventually end up? http://factordb.com/index.php?id=1100000000852525404 Edit: Doing so, it actually works.

Oh, missing the "i" for starters. Except for that, a better one here in my opinion. Total factoring time = 14350.3348 seconds Last fiddled with by storflyt32 on 2016-08-06 at 03:22 |

http://factordb.com/index.php?id=1100000000852798907 Perhaps a little too much in the first link when it comes to expectations. Sorry about that. Please have me excused. Became the wrong set of factors this time, but only goes to show that a given number may not be factored by only 2*3*5*7 and so on. Edit: http://factordb.com/index.php?id=1100000000852799711 http://factordb.com/index.php?id=1100000000852801157 The strange thing is that the first one, where I am still trying to working out the better pair by means of ecm does not help much when it comes to the remaining part of the factorization. Nice pair here by the server. Last fiddled with by storflyt32 on 2016-08-08 at 01:40 |

Left the computer running while away and came back to having the large pair being factorized by means of ecm.
A couple of other things lying around here as well, while others are still waiting to be run. At least it shows that this is possible. Also I happened to write expectancies first. Apparently both words could be used. Last fiddled with by storflyt32 on 2016-08-08 at 16:50 |

Is 2^156165461-1 perhaps a prime number?
Where are the conjectures? Last fiddled with by storflyt32 on 2016-08-12 at 02:20 |

For example, 3 exactly divides 15. Or, similarly, 4755811727022793 exactly divides 2^156165461-1. So, no, 2^156165461-1 is not a prime number. Without "perhaps". |

http://factordb.com/index.php?id=1100000000853732434 Which of these ones above is perhaps cheating and which one is not? Anyway, Total factoring time = 9010.9624 seconds for the second one. Last fiddled with by storflyt32 on 2016-08-14 at 19:05 |

Ah, Batalov.
Sorry about that, but your post slipped my eyes in the light of the day and I did not catch the good meaning. Thanks for telling me! Last fiddled with by storflyt32 on 2016-08-15 at 02:59 |

http://factordb.com/index.php?id=1100000000853974339 Should tell. Only a coincidence this time when it comes to the first one and not intentional in any way. Such a thing happens at times. Working on the second number right now. Edit: Just in the door. The second one "divides" from the C1133 with a P11, P13 and a PRP711. http://factordb.com/index.php?id=1100000000853979768 http://factordb.com/index.php?id=1100000000853980282 Ending back at the second link at the top of the post.
