Factors of 25: 1, 5, 25 Factors of 42: 1, 2, 3, 6, 7, 14, 21, 42
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.
42 = 1 x 42 42 = 2 x 21 42 = 3 x 14 42 = 6 x 7
The Greatest Common Factor (GCF) is: 6
(21,1)(7,3) (42,1)(21,2)(14,3)(7,6) Since 21 is a factor of 42, all the factors of 21 will be included in the factor pairs of 42.
