All that says is that the factorization produces factors 
(NOT prime factors) that multiplied back to give the 
original number. What is needed are PRIME factors. You 
have to actually look at the last few factors returned in 
Factored Integer; any thing larger than 12399 in that list 
must be a composite and not a prime factor and hence an 
error.

Too bad Wiki right now is not displaying the entire 
result, but your Axiom should display it.
