GCF - What is the highest number possible that the two given terms have in common.

In the given problem, one can clearly see that the two share $c^{2} and d$ .

The factors of 14 are 1, 2, 7 and 14 while the factors of 42 are 1, 2, 3, 6, 7, 14, 21 and 42.
Out of the two, 14 is the highest number that they both share.

Answer:

81(x + 2y)(x - 2y)

Step-by-step explanation:

$81 {x}^{2} - 324 {y}^{2} \\ \\ = {(9x)}^{2} - {(18y)}^{2} \\ \\ = (9x + 18y)(9x - 18y) \\ \\ = 9(x + 2y) \times 9(x - 2y) \\ \\ = 81(x + 2y)(x - 2y)$
