What's the world's highest number?

Answer 1

googolplex. check out this site for some number facts, and links.

Answer 2

Generally speaking- a Google is considered the highest. That's 10 to the 100th power. 1 followed by 100 zeros.

While this doesn't seem like much, there are probably only 10 to the 85 elementary particals in the universe. i.e. the number of electrons, protons and neutrons in the universe. So- 10^100 is pretty dang big.

Answer 3

If we use the following notation:
3∧3=33=27
3∧∧3=3(33)=327=7,625,597,484,987
3∧∧∧3=3∧∧æ
è
3∧∧3ö
ø
=3∧∧7,625,597,484,987=3(7,625,597,484,9877,625,597,484,987ö
ø

3∧∧∧∧3=3∧∧∧(3∧∧∧3)...
then we can construct Graham's number as follows:
consider the number 3∧∧...∧∧∧3 in which there are 3∧∧∧∧∧3 arrows;
consider the number in which the number of arrows is equal to the previous 3∧∧...∧∧3 number;
continue this process for sixty-three steps.
This number is Graham's number; thought to be the largest ever occurring in a real mathematical problem (it is listed in the Guinness book of records as the world's largest number). It occurs in a problem in combinatorics.

Answer 4

Neat Question!

I think the reason that you are having trouble finding the answer is
because there is no answer.

Let's see why.

1,000,000,000 (1 billion) can't be the largest number because
1 billion + 1 is bigger.

But that is true for any number you pick.

You can pick any big number and I can pick a bigger one just by adding 1 to it.

Mathematicians make up a name for the quantity bigger than all
the numbers. They call it infinity, but infinity isn't a number, it is
just a name for the thing bigger than all numbers.

Hope this makes sense to you,

Answer 5

no one knows because no one has ever reached it . if a computer started counting from 1 upwards and counted a million numbers per second, in 100 years it would have reached 555,555,555,555,555,555,555,555,555,555,etc. etc. in fact 5 to the power of 555,555,555,555,555,555,, i can't even say it but i did work it out once , it will be 5's because to get to 6's will take another 20 years. try it and you won't wanna stop .lol actually i made the whole thing up but it was kinda fun .what a saddo !!

Answer 6

I will create the world's highest number for you. Let's say that F1(n) = n^(n^(n^...)) to n terms. Let's say that F2(F1(n)) = F1(F1(F1(....))) to F1 terms. Let's say that Fn repeats this nested process n terms. We let n be any large number. Fn(n) is now some stupendously large number that cannot be even written down in the space of the entire universe even if the digits were as small as atoms. it cannot even be written down in THIS universe or the next! How about that? I've just created the world's highest number, Fn(n). Where's my Fields Prize?

Answer 7

Infinity

Answer 8

There isn't one.Whatever it would be you would only have to add 1 to it and it would no longer be.

By the way Morey000 a googleplex is 10 to the power of a google. MUCH bigger!!!

Answer 9

There is no highest number because the number can go higher and higher indefinitely:
11111111111111...........can go on forever---If that is what you meant.

Answer 10

There is only 1 world, so i reckon 1.
