(ID: 225399) 21079064065877605827352405119351832289326203806807496326008325673401073888460606664955308236820248900336131629 (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.
