Factor a list of integers?
Is there an easy way to factor a list of integers that are in a text file? I use Wolfram Alpha to factor individual ones and factordb.com to factor a set of integers that fit into a pattern it can handle. But I have a text file of integers to factor that is too large to do individually. Bubba73 You talkin' to me? 02:36, 20 February 2024 (UTC)


 * I'm fairly certain this can be done using Wolfram Mathematica, which however is $$$ even for personal use for hobbyists. Depending on your platform, most of the free systems listed at can be used. For example, if you know and can run Python, you can use SymPy.  --Lambiam 09:48, 20 February 2024 (UTC)
 * With the free online version of Wolfram Alpha, I sometimes hit the computation time limit. I think that paying for the pro online version only gives you 2-3 times as much computation time, which wouldn't be enough.  And buying Mathematica is pretty expensive.

 * I know that I should know Python, but I don't. Bubba73 You talkin' to me? 20:04, 20 February 2024 (UTC)


 * Also, Alpertron is apparently open source. GalacticShoe (talk) 09:57, 20 February 2024 (UTC)


 * That seems to have a file upload! Bubba73 You talkin' to me? 20:04, 20 February 2024 (UTC)

That Alpertron website does a WONDERFUL job!!! Bubba73 You talkin' to me? 01:52, 21 February 2024 (UTC)
