Answer 7

Well, for your first step, you list all the prime numbers in that range. Those are definite for inclusion among the set of numbers for your final solution. Then you take all the other numbers, one by one, and find factors for them that are of the form:

a x b = n

Answer 8

For example:

throw "40" out because 2 x 20 = 40
throw "39" out because 3 x 13 = 39
throw "38" out because 2 x 19 = 38

etc.

Answer 9

When you come to 37, there are no factors for 37, so 37 is one of your numbers.
