A '''prime number''' is an integer (whole number) greater than one that is divisible only by itself and one. There are an infinite number of prime numbers, the first few of which are 2, 3, 5, 7, 11, 13, ….

== Prime factorization ==

By the ~~[[wikipedia: Fundamental theorem of arithmetic~~|fundamental theorem of arithmetic]], any [[ratio]] can be uniquely represented by a product of prime numbers through prime factorization. It enables the notation of ratios as [[monzo]]s.

By the {{w|fundamental theorem of arithmetic}}, any [[ratio]] can be uniquely represented by a product of prime numbers through prime factorization. It enables the notation of ratios as [[monzo]]s.

== Prime equal division ==

A prime equal division is an [[equal-step tuning]] that divides a given [[~~equave~~]] into a prime number of pitches. They are notable because of many interesting properties.

A prime equal division is an [[equal-step tuning]] that divides a given [[interval]] into a prime number of pitches. They are notable because of many interesting properties.

== Coprime numbers ==

Two integers are '''coprime''' if they have no divisor in common except 1.
