Highest Common Factors (HCF) of P(x) and Q(x)

Factor each, and then

**make a table**with the factors:

[HTML]P(x): (x + 1)(x + 2)(x + 4)

Q(x): (x + 1)(x + 2) (x - 5)

----------------------------------

LCM: (x + 1)(x + 2)(x + 4)(x - 5)

HCF: (x + 1)(x + 2)[/HTML]

The LCM is the product of*all*the factors; the HCF (or GCF, for Americans) is the product of only the common factors. (Wink) - October 7th 2009, 03:59 AMsaberteeth
