You have a few choices:
60
59 and 60
There are infinitely many combinations of two numbers which when multiplied by each other will equal 60; I am not going to list all of them. Some examples are, 10 x 6 = 60, 5 x 12 = 60, 2 x 30 = 60, 1.5 x 40 = 60
18x20 = 3 60
1 x 60, 2 x 30, 3 x 20, 4 x 15, 5 x 12, 6 x 10
