What the highest number to get n factorial in windows 7 before getting overflow?

Try the Factorial CalculatorCarey Frisch

Do you mean the WIndows 7 scientific calculator?3248 is the largest integer.(The Windows 7 calculator appears to compute the gamma function, so it accapts non-integer arguments.)The result limit seems to be 10^10000. (Googol to the 100th power, if you like.Much larger than a Googol, much less than a googolplex.)

Why do you need such large factorials, I tested that calculator with 1024! and it choked as expected. 1024! is a larger then the number of protons in the visible universe.

If windows 7 is better than vista why I can factorial larger numbers in vista than in windows 7 calculator'I donot need larger calculator, but windows 7 do

That is not its purpose, if you really need that, go find a large integer package and get Visual Studio and write your own code. Such a function is not a part of an operating system.
