The factor pairs of 28 are 1*28, 2*14, and 4*7
2*2*7
28 = 22x7, or 2x2x7^4 7^2 2
1, 2, 4, 7, 14 and 28 are its factors, so it has six factors.
Greatest common factor= 7 The greatest common factor is the factor that all these numbers have in common. It helps to make a list of all the number's factors. 28- 2, 2, 7 35- 5, 7 42- 2, 3, 7 All of these numbers have 7 as a factor, therfore 7 is the greatest common factor
28 = 2 x 2 x 7 = 22 x 7
2 x 2 x 7 = 28
28 = 7 x 2 x 2
