The prime vertex graph, $\Delta \left( X \right)$ , and the common divisor graph, $\Gamma \left( X \right)$ , are two graphs that have been defined on a set of positive integers $X$ . Some properties of these graphs have been studied in the cases where either $X$ is the set of character degrees of a group or $X$ is the set of conjugacy class sizes of a group. In this paper, we gather some results on these graphs arising in the context of direct product of two groups.
