Factorizations

Primary (ID: 16725) 279151346689444799703543961 (proven prime)
(ID: 16726) 21207295525042162472855035774554920983369112003734609627857536220273502483799182230278455059875669788781250517331923137534301 (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.
