A factor is a number .... the phrase Greatest Common Factor, shortened to GCF is just a shorthand way to tell you to find a GCF.

ex: 20 has several factors -- 1,2,4,5,10 and 20 But there is no GCF until you have 2 or more numbers to compare.

ex; Find the GCF of 20 and 30 --- ans 10. 10 is the greatest (largest) number that is a factor of both 20 and 30.

2 is a common factor, and so is 5, but the GREATEST factor that they have in COMMON is 10
