2 and 28, respectively.

Since their GCF is 7, they must both be multiples of 7. Since their LCM is 28, they must both be factors of 28. The only numbers that are both factors of 28 and multiples of 7 are 7, 14, and 28. It cannot be 7 and 14, because the LCM of 7 and 14 is 14. It cannot be 14 and 28, because their GCF is 14. Therefore, it must be 7 and 28.
