(ID: 163777) 211048658446453269532102297231288792368791774683356401532304175908567298985525769 (composite)

Primary factorization keeps track of the smallest (known) prime factor. Secondary factorizations are old results kept when a new smaller prime factor is found, which occasionally happens with ECM.
