How they're listed.
The factors of 20 are 1, 2, 4, 5, 10, 20
The factor pairs of 20 are (20,1)(10,2)(5,4)
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)
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: 1, 3, 9, 27. Pairs: (1,27);(3,9).
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.
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.
These are the factor pairs:1750,1875,2350,5250,7175,10125,1470,2550,35
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.
1,24
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: 1, 3, 9, 27. Pairs: (1,27);(3,9).
The factor pairs of 26 are the pairs of numbers that, when multiplied together, equal 26. The factor pairs of 26 are (1, 26) and (2, 13). These pairs represent the integer factors of 26.
Factors of 21 are 1, 3, 7, and 21; the factor pairs are (1 x 21) and (3 x 7).
I suggest you split up this number into prime factors. Then you can easily pick out different factors, combining different prime factors. To get FACTOR PAIRS, pick out one factor, then divide 1040 by that factor to get the other factor. For instance, 10 (2 x 5) is one factor; if you divide 1040 by 10, you get 104 as the other factor (so the factor would be 10 x 104).
