We explicitly provide, in a simple way, the form of the conserved quantities of the one-dimensional Hubbard model. The method developed is based in a newly found factorization property of the local transition matrices, which is satisfied by several spin and fermion chain models. In this way, we have shown a systematic method for deriving the conserved quantities of integrable quantum systems.
