14 and 21, and 21 and 28 are the number pairs between 15 and 30 that have 7 as their greatest common factor.
The factor pairs of 51 are (1,51) and (17,3)
The factor pairs of 28 are :28,114,27,4
The factor pairs of 28 are 1*28, 2*14, and 4*7
There are 3 factor pairs of 28. 28 = 1 x 28 28 = 2 x 14 28 = 4 x 7
28 has three factor pairs which are:28 = 1 x 2828 = 2 x 1428 = 4 x 7
Its factors are only itself and one because 7 is a prime number
