The purpose of this paper is to determine the most important growth factors in OIC member states. For this purpose, a sample of these countries has been selected during period 1975 - 2015 and using the Bayesian Maximum Likelihood Approach (BML) in the context of panel data, among the many factors that can affect growth, endogenously and through various exams in many repetitions, the factors that have the greatest impact are selected and introduced as the robust factors. According to the results, saving rates (SR), foreign direct investment (FDI), investment (ISH), total factors productivity (TFP), and research and development expenditures (R & D) have had the greatest impact on economic growth in these countries. The results could be used to build appropriate patterns for explaining economic growth issues in OIC member states and better management of the economic growth process.
