To find what makes 65 in multiplication, we can identify its factor pairs. The pairs are (1, 65), (5, 13), and (13, 5). These combinations indicate that 65 can be formed by multiplying these factor pairs together.
The factor pairs for 20 are: 1 x 20 2 x 10 4 x 5
12, 16 or 18
The factor pairs of 91 are (1,91) and (7,13).
To achieve the result of 20 through multiplication and division, you can use several pairs of numbers. For example, multiplying 4 by 5 gives you 20 (4 × 5 = 20). Alternatively, dividing 100 by 5 also results in 20 (100 ÷ 5 = 20). Another example is multiplying 2 by 10, which also equals 20 (2 × 10 = 20).
20 has 3 factor pairs. Pairs are (1,20), (2,10) and (9,9)
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.

There are 3 factor pairs of 20:20 = 1 x 2020 = 2 x 1020 = 4 x 5
There are 3 factor pairs of 20: 1 x 20, 2 x 10 and 4 x 5.
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 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.
12 and 18 have three factor pairs.
12 and 18 have three factor pairs.
