integer content of a polynomial
expanded polynomial with rational coefficients
icontent computes a rational number such that dividing the expanded polynomial by it makes the polynomial primitive over the integers. Thus, for integer coefficients, icontent returns the greatest common divisor of the coefficients.
For rational coefficients, icontent computes the least common multiple of the denominators of all fractions in addition to the greatest common divisor of the numerators of the coefficients.
The icontent command is thread-safe as of Maple 15.
