Factorizations

Primary (ID: 7601) 19100900655540830489319601 (proven prime)
(ID: 21837) 47970052259069942979227791513152485524434315778652135414761895602670319218785159653550549660800492779383039254395575340221 (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.
