Question

Find the GCF of 18x^5,-14x^6,7x^7

Answer 1

Given,

The expression are 18x^5,-14x^6,7x^7.

Required

The greatest common factor of the given terms.

The factor of the terms are:

`\begin{gathered} 18x^5=2*3*3* x* x* x* x* x \\ -14x^6=-2*7* x* x* x* x* x* x \\ 7x^7=7* x* x* x* x* x* x* x \end{gathered}`

The greatest common factor of 18x^5, -14x^6, 7x^7 is x^5.

Hence, the greatest common factor is x^5.
