To find the greatest common factor (GCF) of 16 and 24, we can list the factors of each number:
Factors of 16: 1, 2, 4, 8, 16
Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24
Now, we identify the common factors between the two sets:
Common factors: 1, 2, 4, 8
The greatest of these common factors is 8.
Thus, the greatest common factor of 16 and 24 is 8.
