What are composite odd numbers?
An odd number is an integer that is not evenly divisible by 2. A composite number is a positive number that has divisors other than 1 and itself. So any odd number greater than 1 that is not prime would be a composite odd number. For example, 9, 15, 21, and 25 are odd composite number because the are odd and they have divisors. 1, 3, 5, and 7 are not composite because they are only divisible by 1 and themselves.
Are composite numbers even or odd?
An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2. Composites can be either.
