WebbEn mathématiques, l' indicatrice d'Euler est une fonction arithmétique de la théorie des nombres, qui à tout entier naturel n non nul associe le nombre d'entiers compris entre 1 et n (inclus) et premiers avec n .

By Lemma 2.1 we know that p˚(n) is the number of numbers relatively prime to n and less than pn. Notice that all the multiples of pwhose factors are relatively prime to n are counted, since gcd(p;n) = 1. Notice the conditions imply gcd(pn;r) = 1 if and only if WebbSince φ(n) is less than n, such a sequence is strictly decreasing and reaches 1 after a finite number of steps. Following Pillai [7], let R(n) denote the smallest integer k such that φk(n) = 1.That is, R(n) is the number of steps it takes the sequence beginning with n to reach 1.
