what's the largest number known to man?

Answer 1

largest named number is probably a "googolplex": 10^(10^100)


it's much bigger than a "googol" (10^100), which btw is not the same speling as the tech company, "google"

Answer 2

The largest number you can name + 1

Answer 3

There is no "largest number known to man," because for whatever number someone knows, n, they know a number larger than it, n+1.

There is a largest known prime though. A list of the top 10 largest KNOWN primes is here:

Answer 4

Although it's really hard to believe, there is NO greatest number known to man as man does not have the knowledge or technology to measure or describe what's probably the prime pretender for the title - the size of the universe.
Oh, and by the way, although infinity is used in math, it's not really a number in the full sense of the word - it does not describe a single quantity. (f.e. for some people it's what goes beyong a billion billions, while for others it's what goes beyond 9.9E99).
When somebody says 'infinity', he/she means he/she doesn't know how large the number is nor has a way to describe it. Otherwise the alternative is ussually 'X' or 'N'.

Answer 5

Aleph-zero. It's the number of all possible round numbers (including infinity), and therefore it has to be greater than all numbers. So it's not really a number, but since it's a count it is a number. Or something.

Then there's the "cardinality of the continuum", which is the number of ALL numbers (fractions, irrationals, everything included). Which is probably aleph-one, but they're not sure if there's anything in between. (And this gets even more crazy: it's been proven that it's impossible to know whether there's anything in between.) So aleph-zero is the largest number we know, 'cause we can't know the next number.

Answer 6

Those numbers on top of that billboard for Philips 66 are pretty big, like 6 foot tall. :)

Just kidding. The set of positive whole integers is infinite. So whatever number you pick, I can pick a larger one. When scientist wish to express the 'largest number' they simple use the symbol for the higher order of infinity.

Answer 7

google X 2

Answer 8

1 * 10 to the power infinity

Answer 9

Mention any large number n and I say that n^n^n is much larger.
So their is no largest one.

Answer 10

Numbers are infinite, meaning there is no end to them, so you can't really proclaim one as the largest.
