What is the largest number known to humankind?

Answer 1

The largest number which has so far been named is "Graham's Number". It is too impossibly large to be written down in any of the familiar ways of writing numbers. There is a special notation invented by Donald Knuth in which it can be expressed.

Of course you can use Knuth's notation to write down a bigger number, but unless there is a reason for it, it would hardly count.

Answer 2

It's not possible to have a largest number. You could keep adding digits to the end of any number.

Unless you mean a specific name, not something like 99999~. The largest I know of is googolplex (1 with a googol zeroes behind it, a googol is a 1 with 100 zeroes behind it).

Answer 3

What they're trying to tell you is that numbers are an open ended system. - No limit.
To any number you can name, you can add 1.
