Do spaces matter? I mean do you mean characters (_ _ _ _) or letters. If it is Roman numerals, you could go MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM (ect.) just wondering. <_<

to clarify, do you mean the length of the word is four letters, or four letters of the alphabet are used in the word? I couldn't quite tell for certain from the previous posts.

Yes to both

  aforsy said:

also, by 'largest' i assume you mean highest value, not biggest length. if it was the second, we could just say something like pi or another irrational and be done.

Highest value

Highest value

To the first answer.......

does this mean that each letter is used once?? <_<

[Guest]

I'm going with...

As of 2008, yotta- is the largest and last SI prefix to be confirmed. (wikipedia)

And that uses four different letters, but the highest SI prefix to use both four characters and four separate letters is peta-

Could you possibly explian that in kid language?? I don't have a great vocabulary. <_<

[Guest]

The answer is four letters long and each letter is a different one from the others. Does that help or is there something else?

[peace*out]

Thanks!! That was perfect!!

[Guest]

How about this one?

e^(e^(e^e))

The number has about one million digits. When you write the number on a paper you don`t write the symbols, you just write smaller 'e's, so it's just using 4 letters, right?

If greek letters are allowed, you could use pi's and it would be even higher.

[peace*out]

May i ask where the 'e's come from??

[Guest]

e is an irrational number with an approximate value of 2.71828. e^e^e^e is approximately 528462751.

wooooooooooooowwwwwwwww!

Never knew that before!!

WOW!

I think though that you have to have each # be different/no number can be repeted.

M.A.T.H.

This is sort of an underground number, and you may have to do some digging.

[Guest]

I have absolutely no idea what that means...

What digs underground? I thought I was practically giving it away here. Anyone take chemistry?

[Guest]

Oh! I see! I should have gotten this from the hint...

Avogadro's number, also called a mole: 6.02214179x10^23. Very big indeed.

[Guest]

yeah I almost failed chemistry and dont know how I passed math.

Must've been my **** smile.

[Guest]

Infinity

using four letter C's you move them around to make the infinity symbol

[Guest]

...unless you say that 'infinity is a concept'

What is the largest known number that can be written with only four letters?

FOUR --- because it's the largest number where the number of letters equals the number itself.. ?
