The first thing we are going to do for this case is write the factors that each of the numbers have.
We have then:
For the number 28:
28: 1, 2, 4, 7, 14, 28
For the number 44:
44: 1, 2, 4, 11, 22, 44
Therefore, the factors that both numbers have in common are given by:
1, 2, 4
Answer:
28 and 44 have in common the fllowing factors:
1, 2, 4
