Is factor of
Algebraic factorization 1 factor · partial

These factors follow from the form of the expression and divide this number; the remaining cofactor still needs numeric factoring.

5 Quotient factor 1 dig
polynomial family: coefficient above max_poly_coeff_digits · 1 candidate(s) of the numerator do not divide the quotient (expected for terms with divisors)
