Abstract: The theorem about primitive divisors in algebraic number fields is generalized in the following manner. Let A, B be algebraic integers, $ (A,B) = 1, AB \ne 0$, A/B not a root of unity, and $ {\zeta _k}$ a primitive root of unity of order k. For all sufficiently large n, the number $ {A^n} - {\zeta _k}{B^n}$ has a prime ideal factor that does not divide $ {A^m} - \zeta _k^j{B^m}$ for arbitrary $ m < n$ and $ j < k$.
