1 and 7
1 and 14, 2 and 7
Its factors are only itself and one because 7 is a prime number
its a factor with two pairs of the same number
1 and 7
The factor pairs of 14 are 1*14, and 2*7
These are the 16 factor pairs for the number 1,080:1080,1540,2360,3270,4216,5180,6135,8120,9108,1090,1272,1560,1854,2045,2440,2736,30
14 = 1*14, 2*7 14 = 1 x 14 ( 1st factor pairs) = 2 x 7 (2nd factor pairs
A square number has an odd number of factors, but a number with an odd number of factor pairs is nothing special.
The factor pairs of 28 are 1*28, 2*14, and 4*7
Number of factor pairs = number of rectangles
The factor pairs of 168 are the pairs of numbers that can be multiplied together to give the product 168. These pairs include (1, 168), (2, 84), (3, 56), (4, 42), (6, 28), (7, 24), (8, 21), and (12, 14). Factors are numbers that divide evenly into a given number, and in the case of 168, these factor pairs represent all the possible combinations of factors that multiply to 168.
There are 3 factor pairs of 63: 63 = 1 x 63 63 = 3 x 21 63 = 7 x 9
