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.

It has 21 zeros, because 'Giga' means 'a Billion'. Thus, one GigaTrillion is 1 Billion-Trillion. A billion has 9 zeros, and a trillion has 12 zeros. However, if you are referring to the United Kingdom, a billion has 12 zeros and a trillion has 18 zeros, so it would be 30 zeros.

number 1 followed by 21 zeros

One sextillion.

The number 1 followed by 100 zeros is called a googol. The number in scientific notation is written 1 x 10100. A googolplex is the number 1 followed by a googol zeros, 1010100.

a sextillion :) i feel clever knowing that

it is infinite. the most zeros in a number that we know today would have to be a hundred zeros. that number is called a google.
