We extend A.B. Mingarelli's method for constructing generalized factorials. Our extension uses a pair of arithmetic functions (x, y), where x is superadditive. When x is the identity function, our generalized factorial reduces to Mingarelli's. A result on the irrationality of the Euler constant within this framework is given. Using Dirichlet convolution, we characterize when two pairs (α, β) and (x, y) generate the same factorials.
