Prime Factorization for the HP15c?
Message #1 Posted by JamesT on 28 Sept 2011, 11:02 p.m.

I was wondering if anyone had a fast prime factorization routine for the HP1Xc calculators they could share? Thanks! James

Don't know if this is fast enough for you, but it seems reasonably quick on my 15c LE. (But then again, what doesn't?) I've adapted this from an old program - I think written for the 65 - which I found somewhere (probably on this site).

Thanks Dave, I'll get it a try on my LE and Voyager 15c and let you know.

James
