The paper extends the method of \textit{C. Paige} [Reliable numerical computation, Proc. Conf. in Honour of J. H. Wilkinson, Teddington/UK, 73- 91 (1990; Zbl 0721.65013)] concerning the (generalized) QR factorization of two matrices to the case of three or more matrices. The method is used to compute both the generalized and the restricted total least squares solutions of linear equations, and to reduce the computational work.
