Verified Answer :

7 and 8 do not belong

Answer:

6 and 9

Step-by-step explanation:

We are given that factor pair 2 and 28,4 and 14, 6 and 9, 7 and 8.

We have to find different factor pair which does not belong with the other three.

Product of 2 and 28=\(2\times 28=56\)

Product of 4 and 14=\(4\times 14=56\)

Product of 6 and 9=\(6\times 9=54\)

Product of 7 and 8=\(7\times 8=56\)

Hence, 6 and 9 does not belongs to other three because product of 6 and 9 is different from the product of other three factors pairs.
