A one to three digit number followed by six zeros is millions
any number containing 100 zeros has 100 zeros but i'm assuming you mean a 1 fallowed by 100 consecutive zeros; that is a Googol or 10,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000
It's a googolplex
Octillion!
This number is Nonillion and it has 30 zeros in it. That's a lot!
Octillion
octillion
no number
That number quintillion.
A one to three digit number followed by six zeros is millions
Septillion
Trillion.
nonillion
uncentillion.
An octillion.
That depends how many zeros follow the 1.
If you meant a number followed by 100 zeros, that would be Google if the number was a 1. If you meant 100 zeros followed by a number, that would be just that number.
