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.

It can be. 6 is a composite factor of 12.

445 is a composite number because it has factors other than 1 and itself. It is not a prime number.The factors of 445 are 1, 5, 89, and 445.The factor pairs of 445 are 1 x 445 and 5 x 89.The proper factors of 445 are 1, 5, and 89 or,if the definition you are using excludes 1, they are 5 and 89.The prime factors of 445 are 5 and 89.The distinct prime factors of 445, since there is no repetition of factors, are the same: 5 and 89.The prime factorization of 445 is 5 x 89.

No, 4 has one prime factor.

Factor it. Once you find a third factor, it's composite.

To prove whether a number is composite, factor it. A number having any factor besides 1 and itself is composite.

A factor is a number or quantity that when multiplied with another produces a given number or expression. Some factors are prime, some are composite (the number "1" is neither.) A composite factor is a factor that can be divided further. 8 is a composite factor of 24. 3 is a prime factor of 24.

A positive integer greater than one must be either prime or composite. It cannot be neither. 2 divides 160. That is, 160 has a factor other than 1 and itself. So it is not a prime and therefore is composite.
