Factorizations

Primary (ID: 11665) 398858013926743539066881263 (proven prime)
(ID: 11666) 21893195480388416043363413029623997551005947737376162811254809158335205873129457141907638902373571752547392968680570606567973 (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.
