Factoring 17^17+2 - HP40GS success, 50G not
in [HP48]

From: Bicky-Bock on 7 Oct 2007 05:42 HP 49G running 1.19-6 & 2.10-7 correctly factor 17^17+2, as does 40GS - however 50G misses the factor 2243 using 2.10-7. Any ideas as to cause?

My 50g running ROM 2.09 gets 7^2*2243*7526729524839697, which matches what I get with PARI/GP. Interesting how it works with ROM 2.10-7 on the 49G but not the 50g.

There are no differences whatsoever between the HP50 and the HP49 firmware... So either you don't have the same flag settings, or you don't run the same program/version -- They who would give up an essential liberty for temporary security, deserve neither liberty or security (Benjamin Franklin)
