Find overlap between 2 arrays?

Hi,

I have two arrays:

A = [806	807	808	809	810	811	812	813	814	815	816	817	818	819	820	821	822	823	824	825	826	827	828	829	830	841	842	843	844	845	846	847	848	849	850	851	852	853	854	864	865	866	867	868	869	870	871	872	873	874	875	876	877	878	888	889	890]
B = [809	810	811	812	813	828	829	830	831	832	833	834	835	836	837	838	839	840	852	853	854	855	856	857	858	859	860	861	862	863	876	877	878	879	880	881	882	883	884	885	886	887	899	900	901	902	903	904	905	906	907]

Now I want to know which specific numbers (so not the index (since these numbers represent indices), are part of A and B. How can I do this?
