You mean PARI/GP? It is a computer program for number theory
calculations: http://pari.math.u-bordeaux.fr/

After re-booting HP 50G number now factored by FACTORS correctly - besides
false factoring I noticed no other problems. Serial Nr CNA 61807444.

Perhaps your flags settings caused slower operation of FACTOR.

I think FACTOR times out after 1 min. if it can't find any factors.

Please see a post I wrote awhile back:

http://groups.google.com/group/comp.sys.hp48/msg/259cacd1cfc6843e

This might not be the problem, though, since my 49g+ only takes ~6 seconds
to factor 17^17+2, which is nowhere near 60s.

I wish they would omit the 60 second time-out. Since ON would break
the routine anyway, they should have left it to the user to break.

In your post, you said that the 50g took 532 seconds to factor 2^67-1.
A HW2 TI-89 took 213 seconds. I wonder what kind of algorithm those
guys in Texas are using. Then again, the FACTOR routine is probably
emulated on the ARM machines.

Of course, PARI can factor this in 15 ms. :)
