Is Google a Number?

I remember my math teacher saying google was the biggest number possible a few years ago.
Back then I believed him but now that I'm thinking about it, can't be true.
Is not possible for any number to be the biggest possible because numbers are infinite.
Is the word google a number? If the answer is yes, which number is it?

The work Google is a misspelling of the word "googol" which refers to the number represented by a 1 followed by one-hundred zeros.

It means there are 100 zeros after it.
For example:

10000000000...

The term was coined by Milton Sirotta, nephew of American mathematician Edward Kasner, and was popularized in the book, "Mathematics and the Imagination" by Kasner and James Newman.
Google founders chose this name because they were geeks and they liked it.
