Factorizations

Primary (ID: 464) 50354633016533380504238521909 (proven prime)
(ID: 9476) 84995304455058120262215297318911463604172110630585657993041275749245625331156967371793118545667220484647186882582765371657 (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.
