The Euler totient function is relevant for:

Who is this topic relevant for?

  • φ(8) = 4, because the numbers 1, 3, 5, and 7 are relatively prime to 8.

    • While both concepts deal with the properties of integers, they are distinct. The number of divisors of a number counts the total number of divisors, including those that are not relatively prime. In contrast, the Euler totient function only counts the number of integers that are relatively prime to the given number.
