what is the highest known number?

Question

what is it?even though its not used...

i know its infinite...im just asking for the highest KNOWN one...

Answer 1

Well the truth is that there can be no largest number because no matter what the number is you can always add 1 to it.

But some interesting LARGE numbers to exist. In the show Cosmos by the late Carl Sagan, he talks about two such LARGE numbers called google and googleplex, but first please read below:

Here's just a little idea about numbers:

A 1 followed by 6 zeros is = 1,000,000 (one million)
A 1 followed by 9 zeros is = 1,000,000,000 (one billion)
A 1 followed by 12 zeros is= 1,000,000,000,000 (one trillion)

and so on by adding three zeros successively you get:

quadrillion, quintillion, sextillion, septillion, octillion, nonillion, decillion and so on. Most of these numbers you would probably NEVER use.

But get this,

one google = A 1 followed by 100 zeros (whew!)

But here's the real sinker:

one googleplex = A 1 followed by a GOOGLE zeros!!!!

According to the show Cosmos, if somebody actually sat and tried to write a GOOGLEPLEX would a require a strip of paper so long that even if folded and folded and folded into smaller pieces could not be contained in the whole universe.

I don't think we will reach a GOOGLEPLEX very soon, but I'm going to create history for you:

GOOGLEPLEX + 1 (now that is a number that is even bigger, though maybe just a little)

Answer 2

I would say it was the highest known number plus 1. But then someone could add one to my number. Another person might add 10 or 100. That's what infinity is all about. You can keep adding forever.There is no highest known number. It takes less than a second to disprove the highest number by adding 1.
You must have a very low IQ if you couldn't figure that out on your own.

PS It doesn't matter how many zeroes you put in front of a 1. It's still only 1.

Answer 3

There is no such thing as a highest possible number. No matter what number you have, there is always a larger one. (For example, you could always add 1 to your number to get a larger number).
What you are intending to ask is "what is the largest number that anyone has ever decided to give a specific name to?" It is very important to understand that this is a completely different question from the one you asked, because it is a question about human culture not about mathematics.

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 10^(100) (a 1 followed by 100 zeros).

However, there would be nothing stopping you from giving a special name to a still larger number (such as a googleplex plus 1), and then that would become the largest named number once the term became commonly known.

In summary, then: the mathematical question "what is the highest possible number" has no answer, because there is no such thing. But the sociological question "what is the largest number that anyone has ever decided to give a specific name to, a name which has become commonly known" is, for now, a "googleplex" (until someone decides to coin a phrase for a still larger number and it catches on and becomes commonly known).

Answer 4

If you count infinity as a number, then infinity is!

Whenever you think you have the highest number, you can always add 1 to it, to make it slightly bigger. The largest number I know the name of is a googol.

A googol is the large number 10^100, that is, the digit 1 followed by one hundred zeros

http://en.wikipedia.org/wiki/Googol

I just read on wikipedia that a googolplex is a 1 followed by a googol of zeros! So, a lot bigger than my previously known high number!!!

And just something slightly interesting (only slightly mind):

The Internet search engine Google was named after this number. The original founders were going for 'Googol', but ended up with 'Google' due to a spelling mistake on a check that investors wrote to the founders.

Answer 5

Somewhere between 1 with 32 zeros after it and 1 with 87 zeros after it. It has been agreed that an event will not happen if its probability is less than 1 divided by 1 with 32 zeros after it (1/10^32). It has not happened, will not happen here or anywhere else in the universe. So if that is the smallest number then its inverse must be the biggest. However, someone has counted all of the elementary particles in the universe and come up with a number of 10^87. So that must be it for now... unless someone finds another universe.

Answer 6

Largest Number With A Name

Answer 7

All numbers are "KNOWN", but only some have been NAMED. There is no largest KNOWN number because you can always add 1. The largest NAMED number that I know of is Graham's Number. It's significantly larger than anything posted so far, including the googolplex. Graham's number is so big that if it were completely written out, it would have more DIGITS than there are particles in the universe. You can find more information at http://en.wikipedia.org/wiki/Graham%27s_number

Answer 8

There is no answer to this question.

I could tell you 1 ka-bill-a-jillion is the higest number, but what about 1 ka-bill-a-jillion and 1 or 2 ka-bill-a-jillion, or 3? There is no such thing as 'the highest number'. Everything can be counted.

If something goes on forever and ever then it is refered to as being infinite, so if you really NEED an answer to this, it would be 'infinity', even though that is not an actual number.

Answer 9

I would say the highest number is "0". It is the only value that can be added to the front or back of a whole number and change it's value. "says Einstein Plus 1"

Answer 10

... of?
... at which moment?
... by?

Perhaps you need to specify. For example, the highest known number of

Mersenne primes

at this exact moment can be (probably) found here--> http://www.mersenne.org

But, known by you and me? by Mr Mersenne at his time? By some kind of galactic intelligence or by God?

Generally and absolutely speaking, when do you say that a number is completely "known"?
Do we really "know" the simple number ONE? Is it only the fruit of a mathematical assumption in Peano's axiomatic formalisation of arithmetics, is it an intuitive concept emerging from the idea of UNITY and SINGULARITY, or is it an highly mysterious kind of Mary Poppin's bag where all of mathematics come from?
Why have us such kind of "innate concepts"?

Does that makes sense to you?
