Totient of n
WebWhat is Euler's totient function? Euler's totient function counts the positive integers up to a given integer n that are relatively prime to n. We have : ϕ ( n) = n ∏ p n p prime ( 1 − 1 p) WebBelow is the visual example of the simple method to compute Euler’s Totient function for an input integer n. Visual example.

WebThis is called Euler's totient function. There are some interesting congruences involving ϕ(n) that don't seem to be mentioned in most of the standard reference texts. For example, … WebThe integer ‘n’ in this case should be more than 1. Calculating the Euler’s totient function from a negative integer is impossible. The principle, in this case, is that for ϕ (n), the …
WebOf fundamental importance in the theory of numbers is Euler’s totient function φ(n). Two famous unsolved problems concern the possible values of the function A(m), the number of solutions of φ(x) = m, also called the multiplicity of m. Carmichael’s Conjecture ([1],[2]) states that for every m, WebEuler's phi function. Euler 's phi (or totient) function of a positive integer n is the number of integers in {1,2,3,..., n } which are relatively prime to n. This is usually denoted φ ( n ). …
