The largest number known so far is called Grahams number. I don't know exactly how big it is, I just know it's bigger than a googleplex. A "google" is a 1 followed by 100 zeros, and a googleplex is a 1 followed by a google of zeros.
Those are known as square numbers, like 4 and 9.

Numbers go on to infinity so there is no way to say that there is a largest number. The largest natural number that is actually used is "Graham's number" which is used in field of math known as Ramsey theory.
Infinity is NOT the largest number named, because infinity is not a number, it is a mathematical representation of the concept that numbers never stop. The real largest number named is centillion or 10 to the power of 303.

Well why not just multiply by 2 and have 2 gazillion or how about 100 gazillion, etc.
