It is called a Googol.
a google
A Pimpindong
There is no special name for that. Just write it in scientific notation, as 10100000.
It would be 101000000 = 10^(106), but it has no formal name.
googleplex
A quindecillion.
Yes it is a number it is a number because that is the name somebody has given to 1 followed by 183 zeros
There is no specific name for a number followed by 23 zeros, seven and eight zeros would be ten million and hundred million respectively (6 is a million and 9 is a billion). The name for a number followed by 21 zeros is sextillion and the name for a number followed by 24 zeros is a septillion. So, for example, 7 followed by 23 zeros would be equivalent to 700 followed by 21 zeros and so would be called Seven hundred sextillion.
a googol? Nope that is 1 followed by one hundred zeros. A googolplex is one followed by a googol zeros. There is no broadly accepted name for 1 followed by one million zeros.
a google
Googolplexian: The worlds largest number with a name. A "1" followed by a googolplex of zeros Googolplex: The second largest number with a name. A "1" followed by a googol of zeros Googol: A large number. A "1" followed by one hundred zeros. There are infinitely many numbers, so there is no longest number.
Novendecillion
An octillion.
A Pimpindong
Some say a googol is 1 followed by 99 zeros & some say it has 100 zeros. I think it's 100. A dotrigintillion is 1 followed by 99 zeros.
The largest number that has a commonly-known specific name is a googolplex, which is a 1 followed by a googol zeros, where googol is 10100 (a 1 followed by 100 zeros).
