Smile who can factor 10^100+27?

I take great interest in factorization.
It is difficult for me to fact 10^100+27,I
have spent about 15 hours to fact it by
using pari/gp which is an especial famous software
in number theory ,but I failed.
Maybe someone could help me ,
Is there any volunteer to help me to
fact it Or give me some advice ?

Here is a start:

Code:
37 x 270270270270270270270270270270270270270270270270270270270270270270270270270270270270270270270270271

37 is the only factor to 2^63.
The cofactor is composite.

Why this number, just out of curiosity?

I estimate it would take about 30 minutes, total, to factor using SNFS and msieve. Msieve's siqs could also tackle it in a few hours on a fast machine, and that's fire and forget. Look msieve up on google and you'll be on your way.

I'm procrastinating before starting my homework... and I was slightly wrong, it only took about 20 minutes.


prp47 factor: 78175003767451466482080068931559338109988065279
prp52 factor: 3457246654880221174947428776620112459038765878240449

I found 37*prp47*prp52=10^100+27 by using Mathematica 6.0.
How did you get the other two factors of 10^100+27?
I think pari/gp maybe the most powerful software in number
theory.Pari/gp have run about 15 hours on my computer ,
but I can't get any factor of it.So I put this problem on this
forum!I can't believe that there is someone who can fact it
just in 20 minutes!
Which software do you use ?thank you .
Note:my operating system is windows.

Read what he wrote, he used Msieve

PARI is great for general number theory. Factorization is not 'general' number theory though, and specialized tools, such as GMP-ECM, Msieve and GGNFS, are faster at this particular task. They cannot help you with anything else in number theory though. If you want to work with polymonial ideals or whatever, PARI is still your application of choice.

Pari is a powerful tool, but many of its primitive parts are not well optimized. The factoring code is many years old by now and modern tools are enormously faster. Your input number factors especially quickly using the number field sieve, which Pari does not have.

Which software do you use ?thank you .
Note:my operating system is windows.
The key is to notice that you can write your number as
(10^25)^4 + 27. Which is a polynomial in x=10^25 with small coefficients, namely: x^4 + 27. Numbers which can be written as polynomials of degree 4, 5, or 6, with small coefficients, are good candidates for factoring using the special number field sieve algorithm. Google is your friend here as well, if you're interested. I believe several generally accessable websites like wikipedia will tell you the basics of the SNFS.

As far as software goes, msieve will take a polynomial you define and produce your factors with no other effort required. Jason has windows binaries available for download (just google msieve). However to get to 20 minutes, I used the lattice siever available with the ggnfs software suite followed by post-processing using msieve. If you don't know what any of that means, start seaching for those terms. If you have other questions, feel free to post them here.

Good luck and have fun!

Whoa: .00093 sec./relation.

Doing this on a dual-core laptop now. I saw your 20-minute job, and I jumped in. This is only the 4th or 5th time I have used the 4I12e lattice siever. We're spoiled -- jobs like this are tiny now.

That's why I couldn't resist just factoring it. It's worth it just for the novelty of seeing 16000 new relations every time the screen updates. 0.00034 sec/rel with 4I12e

On a more serious note, I ended up vastly oversieving using the heuristic that I needed 0.8 * (pi(2^25) + pi(2^25)) ~ 3M rels. msieve refused to build the matrix until I had manually pruned this back to 1.2M rels. Is the heuristic broken for jobs this tiny, or is msieve not handleing it right somehow?
