Let phi denote Euler's phi function. For a fixed odd prime we give an asymptotic series expansion in the sense of Poincare for the number E_q(x) of n<=x such that q does not divide phi(n). Thereby we improve on a recent theorem of B.K. Spearman and K.S. Williams [Ark. Mat...
Euler Phi Function Calculator n = In 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 ...

where φ is the Euler phi-function. 3 Proof. Let integer d be such that d|n, and denote A d = {r | 1 ≤ r ≤ n, gcd(r, n) = d}, or what is the same, A d = {r | r = ×d, 1 ≤ ≤ n d , gcd( , n d ) = 1}. Hence it follows that |A d | = φ( n...
