Composite but i just can't list the factors.
It is impossible to list the infinite number of prime numbers and composite numbers.
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.
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.
The only composite number in this list is 91. The others are prime numbers.
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.
The number 1 is neither prime nor composite, so it is not included in either list.
No, because a prime number that has only two factors, 1(which is niether prime nor composite) and itself(prime).
Please note that there are infinitely many prime numbers. An Internet search for "list of prime numbers" will quickly give you a list of prime numbers up to a certain point, for example here: http://en.wikipedia.org/wiki/List_of_prime_numbers Any integer greater than 1 that is not in the list of prime numbers is a composite number. (1 is considered neither a prime number, nor a composite number.)
The numbers 13 and 29 are prime - the one composite number in that list is 27.
Search the Internet for a list of prime numbers - the Wikipedia article on prime numbers might list a few. All numbers between 2-100 that are not prime, are composite. (The number is not counted as prime, nor as composite.)
