In algebra, the content of a polynomial is the highest common factor of its coefficients.
A polynomial is primitive if it has content unity.
Gauss's lemma for polynomials may be expressed as stating that for polynomials over a unique factorization ___domain, the content of the product of two polynomials is the product of their contents.
