Factoring Integer into Primes: HP 48GX  John Ferman  12192008 I have the HP41 PPC ROM which contains a routine for factoring any integer into its prime number factors. I am reverse engineering it to make it run on the HP48GX. But might someone already have done that. Anyone know?

My HP 48SX came with a factoring prg 'built in', among several other prgs in VAR. It factors a 10 digit number in less than half a sec. It shows automatically how long time it takes.

I've written a ListtoAlgebraic routine that will change { 3 3 3607 3803 } to '3^2*3607*3803'.

Re: Factoring Integer into Primes: HP 48GX  Hal Bitton in Boise  12202008 Thank you Gerson, Re: Factoring Integer into Primes: HP 48GX...help with the RPL syntax  Hal Bitton in Boise  12202008 I'm trying to key in and run this program, which Gerson Barbosa was kind enough to post, and have a couple of questions.

Re: Factoring Integer into Primes: HP 48GX...help with the RPL syntax  Hal Bitton in Boise  12212008 Thank you VPN,
I see the light!! The program works beautifully now.
Re: Factoring Integer into Primes: HP 48GX...help with the RPL syntax  Gerson W. Barbosa  12222008 VPN has already been of help. Anyway, this is Joe Horn's program and documentation: http://www.hpcalc.org/hp48/math/misc/prime.zip I've just found my L2A (list to algebraic) program, which I thought resided only in my HP28S memory, here: http://www.hpmuseum.org/cgisys/cgiwrap/hpmuseum/archv018.cgi?read=138380 (Message #8) An even faster program is presented by Joe Horn himself in message #9, which I hadn't read yet. Thanks, Joe! Regards,
Gerson.
