1. Find all possible factors of:
(a) x²y
(b) xy²
(c) List those factors common to x²y and xy².
(d) Of all the common factors of x²y and xy² which you listed out in

(c) identify the one that contains all other common factors of x²y and xy² as its factor.
2. Repeat question (1) for x²yz, x²y²z and x²yz².

In your responses in Activity 5, you have been finding common factors for two expression and common factors are important in simplifying algebraic expressions. Given two terms in algebraic expression the common factors are those expressions which divide both of them.
