Euler's totient function φ ( n) is the number of positive integers not exceeding n that have no common divisors with n (other than the common divisor 1). In other words, φ ( n) is the number of integers m coprime to n such that 1 ≤ m ≤ n . (Note that the number 1 is counted as coprime to all positive integers including itself.)
Euler's Totient φ(n) Calculator - Online Phi Function
www.dcode.fr › euler-totientEuler Phi totient calculator computes the value of Phi(n) in several ways, the best known formula is $$ \varphi(n) = n \prod_{p \mid n} \left( 1 - \frac{1}{p} \right) $$ where $ p $ is a prime factor which divides $ n $. To calculate the value of the Euler indicator/totient, the first step is to find the prime factor decomposition of $ n $.
Euler Phi Function (Totient) Calculator
www.had2know.com › academics › euler-totientIn number theory, the Euler Phi Function or Euler Totient Function φ (n) gives the number of positive integers less than n that are relatively prime to n, i.e., numbers that do not share any common factors with n. For example, φ (12) = 4, since the four numbers 1, 5, 7, and 11 are relatively prime to 12. For small integers, it may be easy to simply enumerate and count the number of relatively prime integers less than n.
