Factorizations

Primary (ID: 81550) 85865099174933346147014689 (proven prime)
(ID: 81551) 250594759104166072901736804603772655915792173446930920484244590503809 (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.
