### Abstract

In the paper the following explicit formulae for the prime counting function π are proposed and proved:

where τ is the number-of-divisors function, θ is either the sum-of-divisors function σ or Dedekind function ψ and ⌊⌋ is the floor function. Also an important general theorem (see Theorem 5) which gives an exact formula (depending on an arbitrary arithmetic function with strictly positive values, satisfying certain condition) for the prime counting function π is formulated and proved. This theorem generalizes all other main results in the paper.
