Abstract
This paper investigates the scenario where two operators share the same range, which has proven to be highly beneficial in practical applications, especially for efficiently computing the Moore-Penrose inverse of specific operators. We establish specific conditions under which the reverse order law holds for Moore-Penrose inverses. Furthermore, we explore the relationship between the ranges and Moore-Penrose inverse of operators involved in a factorization $A = BDC$ within the framework of a Hilbert $C^*$-module.
