(ID: 225017) 1689139102442012792776765259852966567188099025229802703125076174448310398879913649239620905166154174355554476073 (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.
