This paper present a comparative study of the various types of positive factorial functions, among which include the conventional factorial, double factorial, quadruple factorial, superfactorial and hyperfactorial. Subsequently, an extension of the concepts of positive n! to negative numbers –n! is introduced. Based on this extension, a formulation of specific generalization cases for different forms of negative factorials are analyzed and presented.
