Prime number

A natural number 𝑛 ∈ℕ is called prime iff it has exactly two divisors in ℕ, namely one and itself.¹ num The first 25 primes are

2,3,4,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,97,…

Prime numbers admit generalizations to two different concepts in the setting of a ring: The Irreducible element and the Prime element.
