A prime number (or prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. By Euclid's theorem , there are an infinite number of prime numbers. Subsets of the prime numbers may be generated with various formulas for primes .
In 2009, N-Dubz won Best UK Act at the MOBO Awards and released their second album, Against All Odds. It charted at number six and was certified platinum, preceded by their first top-10 single "I Need You".

N-Dubz have won four MOBO awards; Best Newcomer in 2007, Best Album for their debut album Uncle B ) and Best Act in 2009 and Best Song in 2010 for their single ...
This property implies that no Euclid number can be a square. For all n ≥ 3 the last digit of E n is 1, since E n − 1 is divisible by 2 and 5. In other words, since all primorial numbers greater than E 2 have 2 and 5 as prime factors, they are divisible by 10, thus all E n ≥ 3 + 1 have a final digit of 1.
Ω(n), the prime omega function, is the number of prime factors of n counted with multiplicity (so it is the sum of all prime factor multiplicities). A prime number has Ω(n) = 1. The first: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37 (sequence A000040 in the OEIS). There are many special types of prime numbers. A composite number has Ω(n) > 1.
Greatest Hits is the first compilation album released by British trio N-Dubz, released following the announcement of the group's plans to go on a two-year hiatus. It was released in the United Kingdom on 28 November 2011 by Island Records .
In particular, τ(n) equals the product of the incremented by 1 exponents from the prime signature of n. For example, 20 has prime signature {2,1} and so the number of divisors is (2+1) × (1+1) = 6. Indeed, there are six divisors: 1, 2, 4, 5, 10 and 20. The smallest number of each prime signature is a product of primorials. The first few are:
