Kryger [21]

Answer:

Step-by-step explanation:

The greatest common factor (GCF) is the highest factor of two numbers...

4 (4) = 16

3 (4) = 12

4 is a factor of both 12 and 16. It is also the greatest factor of the two numbers. For example, 2 is also a factor of 12 and 16. However, it is not the greatest number... 4 is.
