Question

What is the GCF of 3x3^3 - 27x?

Continue Factoring this problem.

Answer 1

`3*3^3-27x=3*27-27x=27*(3-x)\\\\Answer:\ \boxed{GCF(3*3^3,\ 27x)=27}`

Answer 2

For this case we have that by definition, the GFC of two numbers is the largest number that is a factor of both numbers.

We have the following expression:

`3*3 ^ 3 - 27x =`

This can be rewritten as:

`3 * 3 * 3 * 3- (3 * 3 * 3) x =\\3 * 3 ^ 3-(3 ^ 3)x =`

It is observed that if we take common factor, the largest factor will be given by
`3 ^ 3 = 27`

Thus, the GFC of the given expression is 27

Answer:

27
