There are two correct answers to this question:
15 in the USA and other countries using "short scale" naming conventions;
24 in countries using "long scale" naming conventions.
The scales goes as follows:

A billion is one with nine zeros after it. A quadrillion is one with fifteen zeros after it, a googol is one with one hundred zeros after it, and a centillion is one with three hundred and three zeros after it. So it is a centillion.
A googol. It is a 1 with 100 zeros after it.
yes its one hundred thousand trillion :) 17 zeros wow. This is also known as 100 Quadrillion
Negative one with twenty-five zeros is negative ten septillion.
One million trillion billion googolplex =10,000,000,000,000,000,000,000,000,00010100 but the progression is: thousand - 3 zeros million - 6 zeros billion 9 zeros trillion - 12 zeros quadrillion - 15 zeros quintillion - 18 zeros etc, googleplex - an inconceiveably large number equal to ten times the amount of a number that would be 10 with a hundred 0's behind it, or 100,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000, 000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000
A quadrillion has 15 zeros, so there would be 15 zeros in a quadrillion miles.
There are 15 zeros in a quadrillion. 1,000,000,000,000,000

One quadrillion = 1,000,000,000,000,000There's 15 zeroes in one quadrillion.
The number five quadrillion will have approximately 15 zeros.
There are no zeros in "gaudrillion" as the word does not exist.However, Quadrillion, does.Long: 24Short: 15
One quadrillion = 1,000,000,000,000,000 = 1 × 1015, thus 15 zeros.
hundred quadrillion
One quadrillion
Quadrillion definition1. a cardinal number represented in the U.S. by 1 followed by 15 zeros,and in Great Britain by 1 followed by 24 zeros.
"Forthtillion" doesn't appear in any of my reference works. If you mean quadrillion, that's 15 zeros. If you made it up, you can have as many zeros as you want.
Quadrillion
