Well, first you need to know the factors of 28..
1, 28
2, 14,
4, 7
Now add up the different factors, and see what you get.
1 + 28 = 29
2 + 14 = 16
7 + 4 = 11
so your answer, as shown in bold, is 7 and 4.
27 28 29 30
The average of the two odd integers is 28. Therefore the two integers are 28-1 and 28+1, i.e 27 and 29.

First you need to find the prime factors of 28 and 42. 28= 7x22 42= 7x3x2 Then you multiply 7x3x22, the product of which is 84, which is your answer.
prime factors of 28= 2,7
The prime factors of 28 are 2 and 7. Their sum is 9.
4 and 7
4 and 7
4 & 7
28 = 2 x 2 x 7 2 + 2 + 7 = 11
