There is not last number of numbers. In the binary system, or for any system for that matter, you could always add digits to it and the number would increase by at LEAST a power of 10.\n\nInfinity could be the last number, but contrary to popular belief, it is not a number, rather a term stating that something has no end

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

By most counts 192, but it is not as simple as that.  Many places that consider themselves countries are not included in that number - for example, Scotland, Taiwan, Bermuda, Greenland, Western Sahara, Palestine, etc.\n\nThese links should help.

2 (to the power of) 30,402,457 - 1\n\nIt's ten million digits long....!!!  That's crazy.  It was only discovered last year too.\n\nBy the way, you can find out stuff like that so easily by googling

Actually, the largest number named and known is Graham's Number; it is the upper limit to the solution to a problem in an area of Combinatorics called Ramsey-Hunt theory.\n\nTo put it in context, if every particle in the universe were a pot of ink, and you had an infintely large sheet of paper, you would run out of ink before you wrote out the decimal expansion of Graham's Number.\n\nLast I heard--about three years ago--it was the largest number for which any use had been found

As to the highest named number, it is a googolplex, which is a one followed by a googol zeros. As to what a googol is, it is the digit 1 followed by one hundred zeros. So a googolplex is the digit 1 folloed by a googol (1 followed by 100 zeros) zeros. AS for the highest real number, there isn't one. You can always add one more.

the largest that has been calculated is the 43rd Mersenne Prime\n\nOn December 15, 2005, Dr. Curtis Cooper and Dr. Steven Boone, professors at Central Missouri State University, discovered the 43rd Mersenne Prime, (2^30,402,457)-1. The discovery is the largest known prime number \n\nThe new prime is 9,152,052 digits long. The URL below gives it in full, all 9,152,052 digits of it!

Globally, 12,672. Believe it or not.

yep, the others have it right, Mt Everest, at 29,028 feet (not gonna covert to meters, I just don't feel like it) on the border of Tibet and Nepal, is the highest point on Earth.

32 thousand is way off it's alot more then that world wide.  There is no way to really answer this question.  You would have to find out how each country is doing then add them all toghter.

According to Pi World Ranking List the current verified world record holder for reciting the most digits of Pi is Hiroyuki Goto who achieved 42,195 digits in 1995.  However, there is an as-yet-unverified claim that Akira Haraguchi recited 83,431 decimal places in 2005.\n\nMost impressive, indeed.\n\nI hope you found that helpful!

Its 6 billion, I think. You don't you go around the world and count 'em .
