54 = 1 x 54 54 = 2 x 27 54 = 3 x 18 54 = 6 x 9
The difference is between factor pairs and distinct factors. With square numbers, one of the factor pairs will be the same number twice. When listing the distinct factors, that number is only listed once.

(54,1)(27,2)(18,3)(9,6)
Yes, 9 is a factor of 54, because 9 times 6 is 54.
54 = 1 x 54 54 = 2 x 27 54 = 3 x 18 54 = 6 x 9
These are the factor pairs:1750,1875,2350,5250,7175,10125,1470,2550,35
Since 54 is a factor of 108, all of 54's factors are common and the GCF is 54 itself.
