For more about modern usage for large numbers, see Large numbers. To handle these numbers, new notations are created and used. There is a large community of mathematicians dedicated to naming large numbers. Rayo's number has been claimed to be the largest named number. [5]
The following table lists the progression of the largest known prime number in ascending order. [3] Here M p = 2 p − 1 is the Mersenne number with exponent p, where p is a prime number. The longest record-holder known was M 19 = 524,287, which was the largest known prime for 144 years. No records are known prior to 1456.
In 1977, Gardner described the number in Scientific American, introducing it to the general public. At the time of its introduction, it was the largest specific positive integer ever to have been used in a published mathematical proof. The number was described in the 1980 Guinness Book of World Records, adding to its
Rayo's number is a large number named after Mexican philosophy professor Agustín Rayo which has been claimed to be the largest named number. [ 1 ] [ 2 ] It was originally defined in a "big number duel" at MIT on 26 January 2007.

Examples of large numbers describing everyday real-world objects include: The number of cells in the human body (estimated at 3.72 × 10 13), or 37.2 trillion [3] The number of bits on a computer hard disk (as of 2024, typically about 10 13, 1–2 TB), or 10 trillion; The number of neuronal connections in the human brain (estimated at 10 14 ...
Such method is 6.7% more efficient than MIME-64 which encodes a 24 bit number into 4 printable characters. 89: Largest base for which all left-truncatable primes are known. 90: Nonagesimal: Related to Goormaghtigh conjecture for the generalized repunit numbers (111 in base 90 = 1111111111111 in base 2). 95: Number of printable ASCII characters ...
Its prime factorization is 2 googol ×5 googol. History In 1920, Edward Kasner 's nine-year-old nephew, Milton Sirotta, coined the term googol , which is 10 100 , and then proposed the further term googolplex to be "one, followed by writing zeroes until you get tired". [ 1 ]
