(ID: 9917) 175931467081655087701545769421075444377857819112384327340846512698965843195568444384109 (proven prime)

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.
