WebLeonhard Euler's totient function, \(\phi (n)\), is an important object in number theory, counting the number of positive integers less than or equal to \(n\) which are relatively prime to \(n\).It has been applied to subjects as diverse as constructible polygons and Internet cryptography. The word totient itself isn't that mysterious: it comes from the Latin word … WebIn number theory, Euler’s totient function counts the positive integers up to a given integer n that are relatively prime to n. It is written using the Greek letter phi as φ (n) or ϕ (n), and may also be called Euler’s phi function. In other words, it is the number of integers k in the range 1 ≤ k ≤ n for which the g.c.d. (n, k) is equal to 1.
