In literature there is an elegant characterization of factor congruences on a distributive lattice. In this paper, we make an attempt such type of characterization of factor congruences on a Core Regular Double Stone Algebra (CRDSA) and we identify that the factor congruences on a CRDSA A with certain elements of A and proved that set of all factor congruences forms a Boolean centre for A. Further Birkhoff centre is dened for CRDSA and nally it is shown that Birkhoff centre of CRDSA is isomorphic to its Boolean centre
