6670903752021072936960, from the reference given below.
The second link, which is a chain of links from the first page, gives the analysis (which was a brute force program).
This number doesn't have a really obvious factorization, I get:
2^20 * 3^8 * 5 * 7 * 27704267971
Okay, NOW do I get the best answer?? ;-)

Do you mean, starting from a blank 9x9 grid, how many different possible valid sudokus can you create?

There is usually only one answer to a sudoku puzzle, as the filled-in answers only allow for one combination.

The answer is probably around 9x9x9
