In this paper we prove the existence of coincidence points and common fixed points for a large class of noncommuting discontinuous contractive type mappings in metric spaces. Moreover, a method for approximating the coincidence points and common fixed points is also constructed, for which both a priori and a posteriori error estimates are obtained. These results generalize, extend and unify several well-known recent related results in literature.
