Answer:

See the entire solution process below:

Explanation:

To find the GCF of the three terms we need to first factor each of the terms separately:

#10a = 2 xx 5 xx a#

#20a = 2 xx 2 xx 5 xx a xx a#

#25a = 5 xx 5 xx a#

The common terms are:

#10a = 2 xx color(red)(5) xx color(red)(a)#

#20a = 2 xx 2 xx color(red)(5) xx color(red)(a) xx a#

#25a = 5 xx color(red)(5) xx color(red)(a)#

Therefore, the GCF is #5a#
