Any product of two or more odd numbers that are larger than 1. For example, 33 = 3*11 is odd and composite.
Look for a table of prime numbers. All the odd numbers that are NOT on this list are composite numbers.
composite numbers are those that have more than 2 factors. all even numbers other than 2 are composite numbers and some odd numbers are composite numbers. numbers that are prime are the numbers that are not composite numbers i hope this answers your question :)
That's an infinite list, started by 9, 15 and 21.
No. All prime numbers except for the number 2 are odd. However, most odd numbers are composite numbers. All even numbers greater than 2 are composite numbers. So, prime numbers do not need to be odd, since one prime number is even. Also, composite numbers do not need to be even.Here are some composite odd numbers:9 = 3 x 333 = 3 x 1175 = 5 x 15
