Factor pairs are just the factors of a number listed in a different way. The factors of 20 are 1, 2, 4, 5, 10, 20 The factor pairs of 20 are (20,1)(10,2)(5,4)
Factors: 1, 3, 9, 27. Pairs: (1,27);(3,9).
The factors of 8 are: 1,2,4,and 8. The factor pairs of 8 are: 1x8 2x4 These are the only two factor pairs
Factors of 21 are 1, 3, 7, and 21; the factor pairs are (1 x 21) and (3 x 7).
All numbers have factors. It is possible to list them as pairs. The factors of 12 are 1, 2, 3, 4, 6 and 12. The factor pairs of 12 are (12,1)(6,2)(4,3)
Factor pairs are just the factors of a number listed in a different way. The factors of 20 are 1, 2, 4, 5, 10, 20 The factor pairs of 20 are (20,1)(10,2)(5,4)
(6375,1)(2125,3)(1275,5)(425,15)(375,17)(255,25)(125,51)(85,75)
36 does.
These are the factor pairs:1750,1875,2350,5250,7175,10125,1470,2550,35
Prime numbers have one factor pair. Composite numbers have two or more pairs. (6,8) and (4,12) are two different factor pairs for 48.
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.

Factors: 1, 3, 9, 27. Pairs: (1,27);(3,9).
The factors of 8 are: 1,2,4,and 8. The factor pairs of 8 are: 1x8 2x4 These are the only two factor pairs
Factors of 21 are 1, 3, 7, and 21; the factor pairs are (1 x 21) and (3 x 7).
Separate the number into prime factors. Then it should be easy to get ALL the factors, simply by combining different prime factors.
The factor pairs of 21 are:1, 213, 7Therefore, the number 21 has two pairs of positive integer factors.
