I'm not sure about really big numbers in AppleScript, but Python ships
with Mac OS X and the code to get your answer (included below) can be
dumped to a ASCII text file named file.py and run with:

python file.py

The Python program (uncomment the line beginning with "#print" to see each step.

#!/usr/bin/env python

p = 1
for i in range( 1, 20 ):
  p = i * p
  #print i, p
print p
