Two factor questions

["Nick Hobson" <nickh@qbyte.org>]

Hi,

I have a couple of questions about the factor function, as applied to  
integers.

1) Does it sort the results by prime (i.e., first column)?  All the  
results I've seen have been sorted, but I notice the manual doesn't  
specify this behavior.  (Unless I'm missing something.)

2) Is it possible to request only the smallest prime factor, rather than a  
complete factorization?

Thanks,
Nick
