Abstrakt: For a positive integer n, we denote by π (n) the set of prime divisors of n. For a group G and a ∈ G , we denote by o(a) the order of the element a. We prove that a finite group G is nilpotent if and only if π (o (a b)) = π (o (a) o (b)) for all a, b ∈ G of coprime orders. [ABSTRACT FROM AUTHOR]
