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)[reply]

I'm fairly certain this can be done using Wolfram Mathematica, which however is $$$ even for personal use for hobbyists.^[1] Depending on your platform, most of the free systems listed at List of open-source software for mathematics § Computer algebra systems can be used. For example, if you know and can run Python, you can use SymPy. --Lambiam 09:48, 20 February 2024 (UTC)[reply]

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)[reply]

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

That seems to have a file upload! Bubba73 ^{You talkin' to me?} 20:04, 20 February 2024 (UTC)[reply]

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

Glad to hear it :) GalacticShoe (talk) 18:06, 21 February 2024 (UTC)[reply]
