Factorizations

Primary (ID: 19303) 768736559421401249042753476963 (proven prime)
(ID: 19470) 33511509953755269843274731837426124199673734351460479045449075431161788378925901317783500958945385980668371138581 (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.
