The number 10,000,000,000,000,000,000,000,000,000,000,000,000 would be called ten undecillion in United States and contemporary British usage, and ten sextillion in traditional British and continental European usage.
It's a googolplex
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
1+ 300 zeros
1 followed by 100 zeros is 1 google (googol).
A one to three digit number followed by six zeros is millions
37 million (37,000,000) has six zeros.
1 followed by 18 zeros is a quintillion.
That depends how many zeros follow the 1.
1 decillion
A nonillion.
A quindecillion.
enneadecillion
Ten Trillions. Note: One followed by Three zeros = 1 Thousand One followed by Six zeros = 1 Million One followed by Nine zeros = 1 Billion One followed by Twelve zeros = 1 Trillion One followed by Thirteen zeros = 10 Trillions
It's a googolplex
That's a tredecillion!
1 followed by 100 zeros is called a google.
I call it "ten to the fifty-two", and I write it like this: 1052
