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 factor pairs of 150 are 1*150, 2*75, 3*50, 5*30, 6*25, and 10*15
The factor pairs of 250 are: 1 x 250 2 x 125 5 x 50 10 x 25
1 The factor pairs of 100 are 1 and 100, 2 and 50, 4 and 25, 5 and 20, and 10 and 10. The factor pairs of 49 are 1 and 49, and 7 and 7. Since the only factor they share is 1, 1 is their greatest common factor.
1 and 500, 2 and 250, 4 and 125, 5 and 100, 10 and 50, 20 and 25, a total of 6 factor pairs.
There are 10 factor pairs for 5,000:5000,12500,21250,41000,5625,8500,10250,20200,25125,40100,50
1 and 10 are a factor pair for 10.
10 has two factor pairs:10 = 1 x 1010 = 2 x 5
1 and 10, 2 and 5
10x1 1x105x22x5
Two of them.
560 is one such.
The factor pairs of 20 are pairs of numbers that can be multiplied together to give 20. The factor pairs of 20 are (1, 20), (2, 10), and (4, 5). These pairs represent all the possible combinations of numbers that can be multiplied to equal 20.
2
There are 3 factor pairs of 20: 1 x 20, 2 x 10 and 4 x 5.
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.
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)
