A prime number or short a prime $p$ is a natural number, which has exactly two divisors, namely its trivial divisors \(1\) and \(p\).

We denote consecutive prime numbers by \(p_i, i=1,2,\ldots\) (for instance, \(p_1=2, p_2=3, p_3=5, p_4=7, p_5=11,\ldots\)) and the set of all primes as \[\mathbb P:=\{p_i,~i=1,2,\ldots\}.\]
