Chart of prime and composite numbers?
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.)
What are the lists of composite numbers?
There are infinitely many composite numbers so a list is impossible. Furthermore, there is no systematic pattern to composite numbers so that it is not possible to give a functional definition either. There are, however, some lists of prime numbers and you can remove these from integers greater than 1 to arrive at partial lists of composite numbers. For composites up to 1 million, see the related link.
What are the 15 composite numbers greater than 50 less than 70?

Is the number 24 a prime or composite?
24 is composite because it can factored or split up as 24 = 3 * 8 for example. Prime numbers, such as 23, can not be split into factors.
To find a composite number why divide by prime numbers?
You could try dividing by composite numbers but the number that you are testing is divisible by a composite number, then it will be divisible by a prime factor of that composite number and that prime factor will be smaller. It is always easier to work with smaller numbers.
What 9 odd numbers add up to 50?
