Question

what is the GCF (-3x, 6x, 12x)

Answer 1

Answer:

3x

Explanation:

First, find the prime factorization of each of the terms:

$\begin{gathered} -3x=-1\times3\times x \\ 6x=2\times3\times x \\ 12x=2\times2\times3\times x \end{gathered}$

Next, pick the term that is common in the three products:

$\begin{gathered} \text{GCF}=3\times x \\ =3x \end{gathered}$

The GCF of -3x, 6x, and 12x is 3x.
