Question

What is the GCF of the terms 14c²d and 42c³d?

A. 2c²d
B. 7c²d
C. 3c
D. 14c²d

Answer 1

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.

So our answer will be 14
`c^(2) d`
