The table below lists the largest currently known prime numbers and probable primes (PRPs) as tracked by the PrimePages and by Henri & Renaud Lifchitz's PRP Records. Numbers with more than 2,000,000 digits are shown.
Primes that remain prime when the leading decimal digit is successively removed. 2, 3, 5, 7, ... "New Largest Known Prime Number". Numberphile. Brady Haran.
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.

97,336 = 46 3, the largest 5-digit cube; 98,304 = 3-smooth number; 99,066 = largest number whose square uses all of the decimal digits once: 99066 2 = 9814072356. It is also strobogrammatic in decimal. 99,856 = 316 2, the largest 5-digit square; 99,991 = largest five-digit prime number; 99,999 = repdigit, Kaprekar number: 99999 2 = 9999800001 ...
For example, 3 is a Mersenne prime as it is a prime number and is expressible as 2 2 − 1. [1] [2] The numbers p corresponding to Mersenne primes must themselves be prime, although the vast majority of primes p do not lead to Mersenne primes—for example, 2 11 − 1 = 2047 = 23 × 89. [3]
Jon Pace, a flight operations finance manager, is credited with discovering the largest prime number currently known. It’s 23.2 million digits long.
Therefore, every prime number other than 2 is an odd number, and is called an odd prime. [10] Similarly, when written in the usual decimal system, all prime numbers larger than 5 end in 1, 3, 7, or 9. The numbers that end with other digits are all composite: decimal numbers that end in 0, 2, 4, 6, or 8 are even, and decimal numbers that end in ...
