Firstly, find any factor pair of 28. For example, the first one is 7 and 4. 7 is already prime, so that is already part of the prime factorization. 4 isn't prime, so we must split that into a factor pair of some sort. In this case, we see automatically that 4=22, and the 2's are prime. So the prime factoring ends there.
Putting everything together, we get 28=7×22
