Factors are expressions that are multiplied together. The factors of 12ab(x +y) are 12, a,b and x+y.
Finding the factors is called factoring. A prime factor is one that can not be factored further.
The factor of a number is a number that you can divide into the original number evenly. For example, 12 can be divided by 1, 2, 3, 4, 6 and 12. Therefore 1, 2, 3, 4, 6 and 12 are called "factors" of 12.
2 and 3 are the prime factors of 12 since 12 = (2)(2)(3).

Exponents are a way of representing repeated multiplication by the same factor. 3 x 3 x 3 = 33
Exponential notation is used to represent repeated multiplication of the same factor.
knowing the multiplication tables and applying those in reverse allows you to factor.
12 x 12 = 144
