comment How to estimate the size of a ratio with very large factorials?
@StevenStadnicki: You are right, I made a stupid beginner's mistake :-( I wanted to estimate $\frac{10^{18}!}{10^{14}!\ (10^{18}-10^{14})!}$

comment How to estimate the size of a ratio with very large factorials?
I tried it in WolframAlpha and it gave me an even bigger result: The highest exponent might even be greater then 19 (which would make a huge difference!) - Input: ((10^18)/e)^(10^18)*Sqrt(2*Pi*(10^18))/(((10^14)/e)^(10^14)*Sqrt(2*Pi*(10^14))*(‌​(10^4)/e)^(10^4)*Sqrt(2*Pi*(10^4)))

I think this is a good starting point but perhaps there are other ideas?!?
