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

Answer: 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.
