Answer 1

there are 4 factors
Factoring is basically finding what you have to multiply together to get an expression.
Note: this is different than scale factors and constants

I believe that the factors are 8, 4 and 2. They're basically numbers you can break down. For example, the factor of 8 is 2 & 4. The factor of 4 is 2 and 2. I hope this helps..
