1) Greg Dresden formula, which requires a computer program.
2) Using Shizuo Kakutani's
but this requires a look up table of 120 digits.
Can you please tell me other than these to approaches, is there any other
for finding the final nonzero digit of n!? If yes, can please give me
Is there any other formula that can be used to solve this manually?
