  Based on the factorization representation of the General Parton Distributions
(GPDs) the momentum transfer dependence was determined by the analysis of the
different representations of parton distribution functions (PDFs) and all
possible experimental data of the electromagnetic form factors of the proton
and neutron. The obtained $t$-dependence of the GPDs is checked by analysis of
the different hadronic reactions (including exclusive and elastic hadron
scattering) in a wide energy region with minimum free fitting parameters.
