Chapter 4.1, Problem 83CCR

To determine

Find the greatest common factor

Answer to Problem 83CCR

The greatest common factor is $2$ .

Explanation of Solution

Given information: Given the pair of numbers $12\text{ and }14$

Calculation:

To get the GCF of each pair of numbers, list down their prime factors and multiply their common factors.

  $\begin{array}{l}12=2\times 2\times 3\mathrm{.....}\left(1\right)\\ 14=2\times 7\mathrm{.....}\left(2\right)\end{array}$

Note that the common factors of this pair of numbers are $2;$

Therefore, its GCF is $2$ .

Thus, the greatest common factor is $2$ .
