Let LΓk and TΓk be finite extensions of algebraic number fields. In the present work we introduce the factor group of k\* & N LΓk J L N TΓk J T by (k\* & N TΓk J T ) N LΓk L\*, where J L and J T are the idele groups of L and T, respectively. The main theorem shows that the computation of this factor
