Composite but i just can't list the factors.

Every composite number can be broken down into its factors, and if you break those factors down as far as you can go, then you have a list of the prime factors of the composite number that you started with.

To find the prime and composite factors of a number, you can list the factor pairs. 92: 1 x 92 2 x 46 4 x 23 The prime factors are 2, 23. The composite factors are 4, 46, 92.

No, because a prime number that has only two factors, 1(which is niether prime nor composite) and itself(prime).

You do! You first list all the factors of a number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.

You do! You list the factors to see if it is prime or not. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.

List their factors. Prime numbers have two factors, composite numbers have more than two.

73 is Prime, therefore there are no factors to list except for 1.

To find the prime and composite factors of a number, list all the factor pairs of the number. Then, go through them and list the primes and composites. 33 1 x 33 3 x 11 The prime factors are 3 and 11. The composite factor is 33. 1 is neither prime nor composite. 18 1 x 18 2 x 9 3 x 6 The prime factors are 2 and 3. The composite factors are 6, 9, and 18.

List the factors. Erase 1 and the prime factors.

The factors of 27 are 1,3,9,27 It's NOT prime it IS composite

yes because 2,3,5,7,11,13,17,19,23,29 are the first 10 prime numbers so if i say list factors of 12 2 is one

The numbers with three or more factors; it's an infinite list.

composite 1, 3, 9

The factors of 12 are 1, 2, 3, 4 ,6, 12. Since 12 has more than two factors it is composite, not prime.

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

Yes. So can you.

There is no prime composite number; an integer greater than 2 can be either prime or composite, but not both. Nor can you list all the prime number and all the composite numbers: you have infinite sets in both cases.

No difference. Once you've found the factors of a number, the prime numbers on that list are the prime factors.

Look up a list of prime numbers (a Google search for "prime numbers" or "list of prime numbers" should do); every number (greater than 1) that is NOT a prime number is composite.

If you want both then it is every number, all numbers are eather prime or composite.

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

The only composite number in this list is 91. The others are prime numbers.

You cannot list all the potential prime factors. Any prime number can be a prime factor. There are an infinite number of prime numbers, so there are an infinite number of potential prime factors. If given a specific number, the prime factors for it can be listed.

The number 1 is neither prime nor composite, so it is not included in either list.
