Prime Challenge Launched by Windows Azure to Find ‘Hidden’ Primes

Businesses, schools or individuals encouraged to search in the gaps between known prime numbers

LONDON, 6th December 2013: The search for prime numbers has always been an important challenge for mathematicians, but now it is being opened up to all. Launched on 29th November (291113) by Microsoft Windows Azure the Prime Challenge invites businesses, schools, universities, clubs or individuals to search for 'hidden' primes.

"The biggest prime number ever discovered is 17 million decimal digits long. Previously, the biggest prime number was 12 million digits long. It's a lot of digits, but there is also a big gap between those two. Potentially there are a lot of "lost primes" waiting to be discovered," said Steve Plank, Cloud Computing and STEM Evangelist at Microsoft.

Prime numbers, defined as those that have no factors besides one and themselves, are at the heart of arithmetic and have numerous functional applications in today's digital world, most notably public key cryptography. The aim of the Microsoft Windows Azure Prime Challenge is to provide a unique opportunity for users from all backgrounds to join the search for more prime numbers.

The challenge is open to all and everyone is encouraged to try and find a "lost prime." To enter the challenge just go to www.primechallenge.org and follow the instructions online.

Steve Plank, Computing and STEM Evangelist at Microsoft, explained: "The identification of new prime numbers is increasingly challenging, but possible for anyone. Forty per cent of the numbers between one and ten are prime but, as we progress up the number line, they taper off and become sparser. But in reality, as we get much further up the number line nobody really knows as nobody has ever searched for them all."

"In order to map large prime numbers of hundreds of digits powerful technology, which can quickly sift through and crunch numbers, is required," Plank continued. "The purpose of the Prime Challenge is to give individuals, organisations, universities and schools the opportunity to access the computing power of our datacentres to find and claim new prime numbers."

Prime numbers play a very important part in today's business world, as they are used to create public key cryptography algorithms. It is these algorithms that are used to secure most online data transfers, including email encryption and bank card security. So nearly all online purchases that are made will use prime numbers in their security process.

The focus of the Prime Challenge is to find the "lost primes"; those prime numbers that have remained undiscovered in the race to always find the biggest prime. As the search for prime numbers has grown mathematicians have always looked as far ahead as possible to find the next biggest prime, leaving plenty of unexplored territory within the number space. The Sieve of Eratosthenes, an ancient mathematical technique to identify prime numbers, dating back to the third century BC, is a simple algorithm that can be used to find prime numbers, which also demonstrates that there is an infinite quantity of prime numbers.

The Microsoft Windows Azure Prime Challenge will run from 29th November (291113) to 29th March (2903). To participate in the challenge, users will need to visit www.primechallenge.org and follow the steps online. To assist with the search all participants can subscribe to a free Microsoft Windows Azure trial giving them up to $200 of free access to create and run virtual machines.
