The isoscaler giant monopole resonances (ISGMR) are computed using the canonical-basis time-dependent Hartree-Fock-Bogoliubov theory (Cb-TDHFB) with five kinds of Skyrme parameter sets (SGII, SkM^*, SLy4, SkT3 and SkI3). To extract the nuclear matter property from finite system, ISGMRs of N=Z (Z=20 - 50), isobar even-even nuclide for A=100, 132 and Sn isotopes are analysed systematically. The magnitude relation of nuclear incompressibility-parameter (K_∞) among Skyrme parameter sets, can be corresponded to the peak positions of GMR in spherical isotopes over A=80. The parameters (K\rm surf, Kτ and K\rm Coul) which appear in expansion of the finite nucleus incompressibility KA, are determined for each Skyrme parameter. From the comparison experimental data whole mass region and the present results, they indicate that the isospin dependent term Kτ is filtered as -305±10 MeV. The incompressibility parameters of \it infinite system corresponding to our results is Kτ^∞=-340±35, K_∞=225±11, and K\rm sym=-138±18 MeV.
