Whats the biggest number in the world that actually EXISTS?

Question

please don't say somethin stupid like 10zilliongzillionmzillionpzillion

Answer 1

The largest number that has a commonly-known specific name is a "googleplex", which is a 1 followed by a googol zeros, where a "googol" is (a 1 followed by 100 zeros).

Answer 2

Well, you can try the biggest known prime, which is
(2^232582657)-1 ; it has more than 9.8 million digits!

Note that if you know any prime number P, you *know* there is a greater prime number than that, it's just tough as heck to find it.

(You would first need to compute ALL the prime numbers less than P. Suppose the prime number P is the n'th such prime, and the k'th such prime is written as P(k); you then have P(1), P(2), P(3), ....,P(n) as the list of all prime numbers known. Now create a new number
Q = ( P(1)*P(2)*P(3)..... *P(n) ) + 1 . You can show that either Q is itself a prime (and therefore much greater than any P(k) ), or it has at least one factor > P(n). )

Answer 3

Hey there!

The largest number in the world is googolplex. Googolplex is the same as 10^googol and googol is the same as 10^100. So googolplex is quite a large number.

Note that infinity is not a number since it does not follow the rules of arithmetic, i.e. infinity+infinity=infinity and infinity*infinity=infinity.

Hope it helps!

Answer 4

Unfortunately, to count my money, I have never needed numbers higher than thousands. On the bright side, I can easily count that high.

Answer 5

All numbers ACTUALLY EXIST. And there's no biggest number. No matter how big a number is, if you add a positive number to it you geta bigger number.
So, 10zilliongzillionmzillionpzill + 1 is bigger than 10zilliongzillionmzillionpzill, no matter how big 10zilliongzillionmzillionpzill is.

Answer 6

the googleplex is the largest number with a name, next is nondecillion.

Answer 7

Somebody in Tanzania is still counting...

Answer 8

infinity and pi are tied for the longest but infinity will always be the hiest value number
