LOS ANGELES, MONDAY - still remember the definition of prime introduced since the start of the primary school level? Yes primes is the number that have only two factors divider, the number 1 and itself. As, 2, 3, 5, and so on.

Recently, a lover of mathematics at the University of California at Los Angeles (UCLA), successfully revealed the largest prime number is calculated that successful so far. Of course, difficult to mention and show the number because it consists of 13 million digits or numbers.

To calculate because it is not easy to be searched Mersenne primes are first introduced mathematician French Marin Mersenne in the 17th century. Numbers are didefiniskan as a result of reduced 2pangkat P 1 with P, which also primes.

The number of found that the value of P 43,112,609. Numbers found a new Mersenne primes to-46. UCLA teams have found eight Mersenne primes with millions of digits.

To calculate the network of 75 computers use the Windows XP operating system. The number has been verified as primes with different algorithms.

"We are very pleased. Now we are looking for the next, although strange," said Edson Smith, head of the team from UCLA. Efforts to find a team is not the largest prime number fruitless because of their success get 100,000 U.S. dollars by the Electronic Frontier Foundation, which makes it as competition, the Great Internet Mersenne Prime Search (GIMPS).

Thousands of people in the world has been participating in the arena. Competition is mengajakan the math lovers around the world use the power of computers to calculate the Mersenne primes are a minimum of 10 million digits.
