One Billion.
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.
One billion is expressed as a 1 followed by nine zeros: 1,000,000,000 1.2 billion then would be expressed a a one, followed by a 2, and then followed by eight zeros: 1,200,000,000
There is no google amount of anything, but a googol is a 1 followed by 100 zeros
There are 100 zeros. 1 googol = 10100 = 1 followed by a hundred zeros.
10 followed by 5 zeros is 1,000,000 (one million). 100 followed by 3 zeros is 100,000 (one hundred thousand) so 10 followed by 5 zeros is greater.
A googol is 10 to the power of 100, and a googolplex is 10 to the power of a googol (or 10 to the power of 10^100). A googolplexian is 10 to the power of a googolplex, which is a number so large it's practically incomprehensible. The number of zeros in a googolplexian would be a 1 followed by a googolplex number of zeros.
7500 followed by 9 zeros; that is 75 followed by 11 zeros in all
1 followed by 18 zeros is a quintillion.
A number followed by 23 zeros is called a "septillion" in the short scale naming system used in the US and modern British English. In the long scale system used in some European countries, it is called a "trilliard." This number is represented by 1 followed by 24 zeros in standard numerical notation.
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.
A trillion is 1 followed by 12 zeros, a sextillion 1 followed by 21 zeros
A one followed by 606 zeros.
