(ID: 17520) 213193329102132860419335457322213078680859806165920368380091936479772538159648560668273 (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.
