Abstract：This paper applies integrating factors method for the generalized Birkhoff systems based on El-Nabulsi fractional order model. Firstly， the definition of the integrating factors for fractional order generalized El-Nabulsi-Birkhoff equations is given； Secondly， the necessary conditions for the existence of conserved quantities of it are obtained； the corresponding conservation theorem is established； Finally， the special case about integrating factors method for this system is discussed.
