A plot of the number of digits in the largest known prime by year, since the electronic computer. The vertical scale is logarithmic. A prime number is a natural number greater than 1 with no divisors other than 1 and itself. According to Euclid's theorem there are infinitely many prime numbers, so there is no largest prime.
It thus improved upon the previous record-holding prime, 6,700,417, also discovered by Euler, forty years earlier. The number 2,147,483,647 remained the largest known prime until 1867. [4] In computing, this number is the largest value that a signed 32-bit integer field can hold.
Largest known primes [ edit ] These numbers have been proved prime by computer with a primality test for their form, for example the Lucas–Lehmer primality test for Mersenne numbers . “!” is the factorial , “#” is the primorial , and Φ 3 ( x ) {\displaystyle \Phi _{3}(x)} is the third cyclotomic polynomial , defined as x 2 + x + 1 ...
New prime is 16 million digits larger than previous one
Furthermore, 114,055,847 is the largest exponent below which all other prime exponents have been tested at least once, so all Mersenne numbers below the 51st (M 82589933) have been tested. [34] ^ ‡ The number M 136279841 has 41,024,320 decimal digits. To help visualize the size of this number, if it were to be saved to disk, the resulting ...
Due to this efficiency, the largest known prime number has often been a Mersenne prime. [12] All possible exponents up to the 48th (p = 57,885,161) have been tested and verified by GIMPS as of October 2021. [13]
The number of bits on a computer hard disk (as of 2024, typically about 10 13, 1–2 TB ... The largest known Smith number = (10 1031 −1) × (10 4594 + 3 ...
The largest number reliably factored [clarification needed] by Shor's algorithm is 21 which was factored in 2012. [23] 15 had previously been factored by several labs. In April 2012, the factorization of 143 = 13 × 11 by a room-temperature (300 K) NMR adiabatic quantum computer was reported by a group. [24]
