Hint: The greatest common factor [GCF] of two (or more) expressions is the largest value which will evenly divide each expression. So, as an example suppose the expressions are 4 and 18. Looking at the divisors of the individual numbers, we see that 2 divides each. That is we could write (4, 18) = 2 * (2, 9). There are no common divisors for 2, and 9 so we are finished and the GCF of 4 and 18 is 2.


EDIT: Note that there is not a unique answer to your problem unless some restriction are made on a and b. I would start by assuming there are no common divisors between a and b (other than 1). Oh, (a³, a⁴) = a³ (1, a)

Since you don't understand the topic, the first step is to study. One method is explained and illustrated here. Using that method, you'd start with the factor table:

factor table:

66 a^3 b^3: 2 3   11 a a a   b b b
    99 a^4:   3 3 11 a a a a

Following the method explained at the link, what is your next step?
