Odd numbers that are not prime include all odd composite numbers. The smallest odd composite number is 9, followed by 15, 21, 25, 27, 33, 35, and so on. These numbers are odd because they are not divisible by 2, but they are not prime because they have divisors other than 1 and themselves. In general, any odd number that can be expressed as a product of two smaller odd integers is included in this category.

What different between odd number and prime number?
While all prime numbers are odd (except 2), not all odd numbers are prime. 9 for example is an odd number, but you can get it by multiplying 3X3, so it is not prime. Odd numbers are numbers that are not divisible by 2. Prime numbers are numbers that cannot be generated by multiplying 2 whole numbers besides 1 and itself.

Is a prime number always an odd number?
Except for 2 all other prime numbers are odd. Otherwise, they would be divisible by 2 (and thus not a prime number). This does NOT mean that all odd numbers are prime, but that all prime numbers (aside from 2) are odd.

Why are all the prime numbers are odd numbers?
All prime numbers are not odd numbers. 2 is an even prime number, and it is the only even prime number because all other even numbers have 2 as one of their factors.
Which numbers illustrate that not all prime numbers are odd?
2 is the only prime number that is not an odd number.
