Centillion is a 1 with 303 zeros so this is the biggest.

No. A googol is 10 to the 100th power (10^100). But the Latin-based named number "centillion" is much larger (10^303 short scale).The largest commonly used number is based on the googol : a googolplex is 10 to the googol power (10 to the 10^100 power)
The only numbers I can think of is a googolplex, and all of the googol family above that, a grahms number, and a skewes number. Hope that helped!!
So far it is a googol. A googol is a number with a hundred zeroes or: 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000

The largest named number that is commonly known is a googolplex. A googol is 10^100 (a one with 100 zeros after it) and a googolplex is 10^googol. Under the traditional naming system of million, billion, trillion, the largest named number is Centillion, which is 10^303 (a one with 303 zeros after it). The largest denomination banknote ever printed was for 1 sextillion (10^21). In science, some large numbers used are Avogadro's number (6.022 x 10^23), which defines the number of molecules in a mole; Graham's number (unimaginably large), which is the upper bound of connections between vertices of hypercubes.
