Prime number

A natural number $𝑛 \in ℕ$ is called prime iff it has exactly two divisors in $ℕ$ , namely one and itself.¹ #m/def/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, \dots

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