The number 2 57,885,161 â 1 has picked up the baton as the largest known prime number, a result that is tremendously exciting for mathematicians, if rather irrelevant to the rest of mathematics. Primes are numbers that can only be divided by themselves and 1, such as 2, 3, 5, 7 and 11.
Demonstration, with Cuisenaire rods, that the number 7 is prime, being divisible only by 1 and 7. A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. A natural number greater than 1 that is not a prime number is called a composite number. For example, 5 is prime because 1 and 5 are its only positive integer factors, whereas 6 is composite because it has the divisors 2 and 3 in addition to 1 and 6.
