Let F q be a finite field with q elements and n= l 1 m 1 l 2 m 2, m 1≥ 1, m 2≥ 1, where l 1, l 2 are distinct primes and l 1 l 2| q− 1. In this paper, we give all irreducible factors of x l 1 m 1 l 2 m 2− 1 over F q and all primitive idempotents in a ring F q [x]/< x l 1 m 1 l 2 m 2− 1>. Furthermore, we obtain the dimensions and the minimum Hamming distances of all irreducible cyclic codes of length l 1 m 1 l 2 m 2 over F q.
