To explain to your son the concept of odd numbers and what they are called in relation to factors, you can use the following explanation:

In mathematics, factors are numbers that can be multiplied together to get a specific result. For example, if we have the number 12, its factors are 1, 2, 3, 4, 6, and 12. This is because if you multiply any of these numbers together, you will get 12.

Now, when it comes to odd numbers, these are numbers that cannot be divided evenly by 2. They always end with the digits 1, 3, 5, 7, or 9. Examples of odd numbers are 3, 7, 13, and so on.

When it comes to factors, odd numbers have an interesting property. Every odd number has at least two factors, which are 1 and the number itself. For example, for the number 9, the factors are 1, 3, and 9. Similarly, for the number 15, the factors are 1, 3, 5, and 15.

So, to answer your son's question, odd numbers also have factors, and they are not specifically called anything different from factors. They simply have a different set of factors compared to even numbers.

I hope this explanation helps your son understand the concept of factors and how they apply to odd numbers.
