A matrix called Varchenko matrix associate with a hyperplane arrangement was defined by Varchenko in 1991. Matrices that we shall call q-matrices are induced from Varchenko matrices. Many researchers are interested the invariant factors of these q-matrices. Shiu put this problem to the graph model. In this paper, invariant factors of Cartesian product of graphs will be found.
