The factorized calculations of the order α3(Zα) 5m to the Lamb shift and factorized corrections of the order α3(Zα)EF to the hyperfine splitting splitting were made. The corrections were generated by the insertion of the three-loop one particle reducible diagrams with radiative photons. The skeleton contribution to the Lamb shift was infrared divergent. Infrared Yennie gauge was used for radiative photons in the calculation.
