The exact expression of the free energy is obtained for the free fermion model on a lattice with a multiple number of sublattices. Compact exact expressions are presented, in particular, for two-sublattice systems. Vdovichenko's method is used in the derivation. Some remarks are given to justify the Vdovichenko's method for the free fermion model.
