Having wasted my time compiling this list of 307 odd 3 digit composites, I would be interested to know what, if anything, you will do with this information.

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
Any product of two or more odd numbers that are larger than 1. For example, 33 = 3*11 is odd and composite.
Work back from 999:999 is odd ... no.998 is even and divisible by 2, so it is composite. (All even numbers are composite!)Further Information:-All even numbers are composite except for 2 which is a prime number.
