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. On October 12, 2024, the GIMPS (Great internet Mersenne Prime Search) discovered 52nd Mersenne prime, the number 2136279841 - 1, which has 41,024,320 digits and is now the largest known prime number. Here we present that number printed, in all its digits, in a single volume. Note: due to the number of digits in the number and the limitations of the physical book, the print is in a very small font.
