What is the largest number ever calculated?

Answer 1

There is no largest number, for numbers are infinite. Infinity is often suggested as an answer, but is only an abstract concept.

Graham's number is the largest number ever denoted (at least, in the context of mathematical proof). This far exceeds the number of atoms in the universe, and is the upper bound for a quantity relating to Ramsey theory; the lower bound is 11.

In a fixed number of characters (letters, numbers, symbols, etc.), the largest number possibly denoted is restricted only by the growth rate of the largest recognised function. At present, Knuth up-arrow notation has the largest growth rate, if enough arrows and large enough integers are used.

Answer 2

The largest number ever calculated is known as Graham's number, which is so large that it cannot be effectively expressed in standard notation. It was introduced in a mathematical proof by Ronald Graham in 1971.

NEVER ENDING NUMBER!!

Answer 4

There never was one. Every time somebody ran into the Math Department office

with a number that he claimed was the biggest in existence, and demanded to

see the Dean right away, the dean's secretary, Miss Graham, would take his

number, add ' 1 ' to it, point out that hers was now bigger than his, and

send him on his way.
