摘要
Given a multiplicative group of nonzero rational numbers and a positive integer m, we consider the problem of determining the density of the set of primes p for which the order of the reduction modulo p of the group is divisible by m. In the case when the group is finitely generated the density is explicitly computed. Some examples of groups with infinite rank are considered.
