3 pairs of factors. They are: 1 and 20 2 and 10 4 and 5 Pairs of factors are numbers that you multiply together to make that number, e.g. 4x5=20. Trust me I'm a teacher!
The factor pairs of 200 are (200,1)(100,2)(50,4)(40,5)(25,8)(20,10) None of them have a sum or difference of 20. Factors of 200 that add to 20 are 10 and 10.
10
100, 50, 25, 20, 10, 5,4,2,1 are the factors and there are 9 of them.
1 and 5 are the factors of 20 which are odd.
The factors pairs of 20 are 1x20, 2x10, and 4x5 so 20 has 6 factors and 5 proper factors.

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)
(20,1)(10,2)(5,4)
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 and 20, 2 and 10, 4 and 5 are all of the pairs of factors of 20.
20 has 3 factor pairs. Pairs are (1,20), (2,10) and (9,9)
The factor pairs of 20 are: 20,1 / 10,2 / 5,4
Twenty only has three factor pairs. (20,1)(10,2)(5,4)
The factor pairs for 20 are: 1 x 20 2 x 10 4 x 5
420 has four prime factors. Prime factors don't usually travel in pairs.
