what is the longest number in the world?
951824
The World Champion largest number, listed in the last Guinness Book of Records is an upper bound, derived by R. L. Graham, from a problem in a part of combinatorics called Ramsey theory.\nGraham's number cannot be expressed using the conventional notation of powers, and powers of powers. If all the material in the universe were turned into pen and ink it would not be enough to write the number down. Consequently, this special notation, devised by Donald Knuth is necessary.\n\nClick on link to see it

The Guiness Book Of World Record officially recognizes aequeosalinocalcalinoceraceoaluminosocupreovitriolic, which contains 52 letters, as the longest word. It is attributed to Dr Edward Strother (1675-1737).\n\nHowever, the longest word currently in the Oxford dictionary is pneumonoultramicroscopicsilicovolcanoconiosis, which is 45 letters long. It stands for a lung disease.\n\nFor more long words, please refer to the source.\n\nFrom a comic angle, the other answrer has already given an answer

4,850,180,331,125,622,098 according to the calculator on Windows. \n\nThis calculator seems to be only 14 characters long, so verification can be done as follows.\nFind the hex eqv for the longest possible number there starting from the beginning. This has already been done in the earlier answer. Next, in the decimal eqv, multiply by 16^2, add 5*16^1 and 2*16^0. That should give you the answer.

rational numbers are numbers that have decimals that end or have decimals that repeat.\n\ne.g. 1.33333333..., 1/3, 2, sq root 4, 3.1212121212..., 3.3233343536\n\nirrational numbers have decimals that cannot be terminated, meaning they can continue on forever.\n\ne.g. pi (mathematical term, not pie for eating!), 3.3233343536... (... is very important because it indicates that the decimals go on, if it doesn't have that then it means decimal ends) sq root 3\n\nhope you understand now :)

The 43rd discovered Mersenne Prime is:\n\n2 ^ (230,402,457) - 1\n\n...which I believe is also the largest known prime.  It must be written in this notation because the actual number is 9,152,052 digits long.  ^.^

The cardinal number equal to 10 to the 21 power.\n\nin Britain it is equal to 10 to the 36 power.\n\nin Germany, it is called a trilliard.\n\n\nFrance (By decree 61-501 of 3 May 1961, modified by decree 75-1200 of 4 December 1975 and 82-203 of 26 February 1982.  Sextillion is the largest number name legally defined. Names ending in “-iard”, though they can still be found in the dictionary, are no longer legal.)

My favorite whole number is 1729.  Why?  Because there is a wonderful and memorable anecdote about that number.  It has been said that one time, when brilliant Indian mathematician Srinivasa Ramanujan was sick on what would be his deathbed, his mentor and friend G.H. Hardy (an excellent mathematician himself) came to visit him and remarked that the license plate of the taxi that had taken him to the hospital was 1729, a number that had impressed Hardy as rather boring.  To Hardy's surprise, Ramanujan immediately replied that Hardy was wrong.  In a snap of the fingers, Ramanujan had come to the realization that 1729 was indeed a very interesting number.  As it turns out, 1729 is the smallest positive integer that can be expressed as the sum of two cubes in two different ways. Indeed, 1729 = 10^3 + 9^3, and 1729 = 12^3 + 1^3.

There is no largest whole number.  No matter how large of a number you can think of, you can add 1 to it and get a larger whole number.\n\nInfinity is not a number; it's a concept.
