WebIn this section, we show that factoring over Q (the rational numbers) and over Z (the integers) is essentially the same problem.. The content of a polynomial p ∈ Z[X], denoted "cont(p)", is, up to its sign, the greatest common divisor of its coefficients. The primitive part of p is primpart(p)=p/cont(p), which is a primitive polynomial with integer coefficients.
