Euler Totient Function

Calculate φ(n) = count of integers from 1 to n coprime to n. For prime p: φ(p)=p-1. For p^k: φ(p^k)=p^(k-1)(p-1).

Euler Totient φ(n)

Calculate φ(n) = count of integers from 1 to n coprime to n. For prime p: φ(p)=p-1. For p^k: φ(p^k)=p^(k-1)(p-1).

How It Works

Calculate φ(n) = count of integers from 1 to n coprime to n. For prime p: φ(p)=p-1. For p^k: φ(p^k)=p^(k-1)(p-1)

Each component has a specific meaning:

  • 1 — The 1 recorded for the scenario being assessed.

Note: Interpret the euler totient φ(n) result against the thresholds and context described above.

How to Use

Enter the 1 for the scenario you are assessing. Calculate φ(n) = count of integers from 1 to n coprime to n. For prime p: φ(p)=p-1. For p^k: φ(p^k)=p^(k-1)(p-1). Use the euler totient φ(n) result to inform your calculation.
