Our progress is dependent on the number of users and advancements in hardware.” Of course, there can be a reward for hunters: GIMPS awards $3,000 for new discoveries, and both the Woltman project and its participants are eligible for the awards given by Electronic Frontier Foundation, which currently offers a $150,000 purse to anyone finding a prime over 100 million digits long. As Woltman tells OpenMind, “GIMPS will continue to forge ahead over the coming years.
This real colossus, M 82589933, discovered on Decemby Florida programmer Patrick Laroche, reaches the unimaginable length of 24,862,048 digits if someone were to try to print it on paper, almost 10,000 sheets would be needed.Īnd the search goes on. The current record is held by the 51 st known Mersenne prime. Since then, all new primes have been discovered by GIMPS users.

In 1996, the American George Woltman, from the Massachusetts Institute of Technology, founded the Great Internet Mersenne Prime Search (GIMPS), a distributed computing project that searches for new Mersenne primes and in which any user can participate by downloading the software Prime95, created by Woltman. The great leap from thousands to millions of digits came about mainly because of one person. In 1989 the largest prime number was 65,087 digits ten years later, Mersenne’s prime M 6972593 reached 2,098,960 digits. That year a new record was set with a 79-digit number, but this number began to grow rapidly with advances in computing. In 1951 computers began to be used to calculate even larger new prime numbers. French monk Marin Mersenne defined the prime numbers that bear his name.

This 39-digit number remains the highest prime discovered by manual calculations. Édouard Lucas himself, a French mathematician, demonstrated in 1876 that 2 127 – 1 is a prime. The Mersenne primes became the mathematicians’ preferred target thanks to tests such as the Lucas-Lehmer primality test, which facilitates verification. Already in 1588, Italian mathematician Pietro Cataldi had shown that 2 19 – 1 = 524,287 is prime, setting a record for his time. If p is a prime number, it is possible, though not certain, that M p is also a prime number. At the beginning of the 17th century, French monk Marin Mersenne defined the prime numbers that bear his name, obtained as M p = 2 p – 1. The Mersenne primesĪfter the Greeks, interest in prime numbers was only revived at the end of the Middle Ages. A century later, another Greek mathematician, Eratosthenes, created a screening method that allows all the prime numbers of a limited list to be identified, simply by crossing out multiples.
demonstrated for the first time that prime numbers are infinite. The first known person to look specifically at this subject was the Greek mathematician Euclid of Alexandria, who around 300 B.C. A young child can understand what makes a number prime, yet lifetimes of mathematical research have been spent trying to solve some of the problems in the field.”
In fact, this apparent simplicity is part of its appeal, according to what Adrian Dudek, a mathematician from Australian National University, tells OpenMind: “I think the fascination for prime numbers comes from the fact that they are so elementary in description but yet incredibly difficult to analyse. The definition of a prime number is so simple that it is learned in primary school: it is that natural number greater than 1 that can only be divided exactly by 1 and by itself. But what is the point of hunting for ever-larger prime numbers? The mathematic papyrus of Amhes.
The data is often cited as a sign that the knowledge and search for these peculiar numbers are almost as old as human thought, a search that has reached almost inconceivable heights in the last couple of decades. More than 3,550 years ago, an Egyptian scribe named Ahmes wrote a papyrus on which he recorded differently those fractions whose denominators were prime numbers.
