In number theory, the Euler Phi Function or Euler Totient Function φ (n) gives the number of positive integers less than n that are relatively prime to n, i.e., numbers that do not share any common factors with n. For example, φ (12) = 4, since the four numbers 1, 5, 7, and 11 are relatively prime to 12. WebbThis article describes the formula syntax and usage of the PHI function in Microsoft Excel.

WebbPhi of seven equals six. So, if you're asked to find phi of 21,377, a prime number, you would only need to subtract one to get the solution, 21,376. Phi of any prime is easy to compute. This leads to an interesting result based on the fact that the phi function is also multiplicative. That is, phi A times B equals phi A times phi B.
