WebSince a number less than or equal to and relatively prime to a given number is called a totative, the totient function can be simply defined as the number of totatives of . For example, there are eight totatives of 24 (1, 5, 7, 11, 13, 17, 19, and 23), so . The totient function is implemented in the Wolfram Language as EulerPhi [ n ]. ari 780/790 standardWeb20 feb. 2024 · And now we are almost done.
