Factorizations

Primary (ID: 219) 3531495042124863863141 (proven prime)
(ID: 882) 5815996275435123148785968296823457529561982453798330749236072397188446827923693513080967643482688537 (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.
