Chapter 7.5, Problem 23IP

To determine

Find the GCF of $40x\text{and}60x$

Answer to Problem 23IP

GCF of $40x\text{and}60x$ is $20x$ .

Explanation of Solution

Given:

Pair of monomials: $40x\text{and}60x$

Concept Used:

GCF is the greatest common factor of the pair of monomials.

Calculation:

  $\begin{array}{l}40x=2·2·2·5·x\\ 60x=2·2·3·5·x\\ \text{GCF}=2·2·5·x=20x\end{array}$

Thus, GCF of $40x\text{and}60x$ is $20x$
