Bryan says that only even numbers are composite

Bryan is in error, and his statement suffers from a marked

paucity of veracity. Not only that ... it's also false.

9, 15, 21, 27, 33, 35, 39, 45, 49, 51, 55, 57, 63, and 69

are just a few of the odd composite numbers.

There are an infinite number of them.

It's true that except for ' 2 ', all other even numbers are composite,

and all other prime numbers are odd.

But that doesn't mean that odd numbers CAN'T be composite.

That's not exactly true. Odd numbers can be composite numbers too. For example 15 is a composite number because it has more than two factors.
