Write all the numbers up to 30 that have an equal number of odd and even factors

2, 6, 10, 14, 18, 22, 26, 30  have an equal number of odd and even factors.

Step-by-step explanation:

Since they want the same number of even and odd factors for numbers 1-30 then we can list the factors of only even numbers from 1-30

List factors of even  numbers 1-30

2,  4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30

2)  1,2

4) 1,2,4

6) 1, 2, 3 6

And so forth for the rest of the numbers

you will notice that you add 4 each time untill you get to thirty which are numbers that have an equal number of odd and even factors.
