Re: 2 questions ...

Hi
I'm new to PARI and need to make 2 functions (to do programming)
If you are comfortable reading english (and your message seems to indicate that you are), you should spend some time reading the documentation provided with Pari/gp. It should be helpful for these kinds of questions. 


1) X^M mod N
(using 3 parameters)


f(X,M,N)=Mod(X^M,N);


2) a function to factorize a natural number...
with natural i refer to:
numbers from 1 to infinite


This is provided by Pari/gp:

? factor(327685558)
%3 =
[2 1]

[29 2]

[194819 1]
In both cases, I have used the syntax for 'gp', the command-line interpreter. The library syntax (for C programming) is a bit different (and is discussed in the documentation). 

Hope this helps.

Regards,

Justin
