Some. Any product of a set of odd numbers will be odd. To be even, a composite number must have at least one even factor. Therefore odd composite numbers must exist.

no55 for example is odd and composite

No. Some composite numbers can be odd.

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

No, some composite numbers are odd. The smallest composite odd numbers are 9, 15, 21, 25, and 27. Not all even numbers are composite either. There's only one even number that's prime, which is 2.

No, they aren't. Numbers like 49 and 27 are odd and composite.

60 is an even composite number. It ends with 0, making it an even number, and all even numbers over 2 are composite numbers.

there are infinity odd composite numbers

The aren't. Two is even and is a prime number. There are many odd, composite numbers.

Even composite numbers can, odd composite numbers can't.

The set of even numbers contains the prime number, 2. The set of composite numbers contains infinitely many odd numbers.

No - although all positive even numbers other than 2 are composite, this does not mean that all composite numbers are even - the first odd composite number is 9, which is equal to 3 x 3.

None of them. All counting numbers are either odd or even.

Any even number is a multiple of two.

It is impossible to list the infinite number of composite odd numbers.

They are odd numbers that do not include prime numbers.

Incorrect. Square numbers are composite and have an odd number of factors.

Composite numbers can have either an odd number or an even number of fractions. Factors of 25 are 1, 5, 25 . (odd number of them) Factors of 26 are 1, 2, 13, and 26 . (even number of them)

The composite numbers in that list are 22 and 36 - you know they are composite, because they are even numbers. The other numbers are odd and prime.
