100
A "Google" google gets its name from the ridiculous number that is a "Google" its a 1 with a hundred 0s behind it. A "Googleplex" is a 1 with a hundred googles behind it
100
Exactly 100.

googol
A 1 followed by 100 zeros is called a googol.
The answer would be 25300. An easy trick to learn is to know that when you multiply by 10 or 100 or 1000 etc all you need to do is add the number of 0s with the given number. If you have for example 25.3 instead first instead of adding 0s, the point moves to the right by one, then when you have no number left add the additional 0s. Example 25.34 times 1000 would be 25340

Quintrigintillion if it's 121 0s. How many 0s is that? I could have counted wrong.

The question, as asked, is difficult to answer, The number of zeros in factorial 100 is not the same as the number of 0s at the end of factorial 100 since there will be some before the end.The answer to the second question is easy:The number of zeros is determined by the number of 10s in the factors.Since 2s are common, this, in turn, depends on the number of 5s.In 100!, there are 20 multiples of 5 each of which will contribute a 5 to the factors of 100!.In addition there are 4 multiples of 52 = 25 each of which will contribute another 5 to the factors of 100!All in all, therefore, there are 24 5s giving 24 0s at the end of 100!
Exactly 100.
