In this paper, a generalized block Broyden's method is presented for solvinga collection of overdetermined equations. We have proven that for the p linear overdetermined equations with a m×n coefficient matrix, the method is terminated with the p least squared solutions after 2m/p steps at most, and two numerical examples are given.
