How do you find the GCF of 14ab, 7a?

Answer 1

Genesis Allen

The GCF is #7a#

We can rewrite #14ab# as:

#2 xx color(red)(7 xx a) xx b#

And, we can rewrite #7a# as:

#color(red)(7 xx a)#

Therefore, the GCF is #7 xx a# or #7a#

To find the greatest common factor (GCF) of 14ab and 7a, you factor each term into its prime factors and then identify the common factors.

For 14ab: 14 can be factored as 2 × 7 ab remains unchanged as it is already in its simplest form

For 7a: 7 can be factored as 7 a remains unchanged as it is already in its simplest form

The common factors are 7 and a. Therefore, the GCF of 14ab and 7a is 7a.
