No. Some composite numbers can be odd.

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 :)

Some are. However prime numbers are always odd, with the exception of the number 2.

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.

there are infinity odd composite numbers

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

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

They are odd numbers that do not include prime numbers.

Look for a table of prime numbers. All the odd numbers that are NOT on this list are composite numbers.

no55 for example is odd and composite

The odd composite numbers lower than 30 are:9 15 21 25 27

Any product of two or more odd numbers that are larger than 1. For example, 33 = 3*11 is odd and composite.

Odd composite numbers.

9 and 15 are the only two odd composite numbers less than twenty.

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

With the exception of 2, all primes are odd numbers, therefore the answer is no.

If an odd number has more than two factors then it is a composite number but if it has only two factors then it is a prime number. Although all prime numbers are odd except for 2 many more odd numbers are composite numbers having more than two factors as for example 21 is an odd number whose factors are 1, 3, 7 and 21.

odd numbers subtraction

The composite odd numbers from 9 to 99.

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

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

Julia is incorrect. 2 is an even prime number and 9 is an odd composite number.

Yes.

An infinite number.

That's an infinite list.
