WebA. Euler’s Totient function Euler’s Totient function symbol is Φ(n), which refers to the number of the positive integers that are less than n and coprime with n. Theorem 1. If n=p·q is the product of two different prime numbers p and q, thenΦ(n) = (p - 1)·(q – 1) Proof.Φ(n) =the number of the positive integers that Web4 Euler’s Totient Function 4.1 Euler’s Function and Euler’s Theorem Recall Fermat’s little theorem: p prime and p∤a =⇒ap−1 ≡1 (mod p) ...

Euler

In 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 or , 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 greatest common divisor gcd(n, k) is equal to 1. The integers k of this form are sometimes referred to as totativ… Weba^(Φ(n)) ≡ 1 (mod n), where Φ(n) is the Euler totient function, which gives the number of positive integers less than or equal to n that are co prime to n. To use Euler's theorem to calculate 20^10203 mod 10403, we need to determine whether 20 and 10403 are co prime, and if so, what Φ(10403) is.
