Numbers that are not prime are numbers that are divisible by integers other than one and itself. Since there are a boatload of these numbers, I will try to keep it brief:
All integers with the last digit 2, 4, 6, 8, or 0 (besides 2 and 0 themselves) are not prime. (Numbers that are not prime are composite. Numbers ending in 2, 4, 6, 8, or 0 are always divisible by at least the number 2, hence they are not prime.)
All integers ending with 5 (besides 5 itself) are not prime (these numbers are always divisible by at least the number 5).
Everything else varies, though. For example, with digits ending with 3, 33 is not prime (divisible by 3 and 11), but 13 is prime. With 7, 17 is prime, but 77 is not (divisible by 11 and 7). Also, two-digit integers with identical tens and ones-place digits are not prime (with the exception of 11); these are all divisible by 11.
That's the general rule of prime vs. not prime. As you can see, it's too lengthy and excruciatingly painful to list ALL of the composites, because they are abundant.

What are numbers that have 2 factors called?
Prime numbers like 2, 3, 5 and 7.
what are the numbers for not prime numbers?
Numbers that are not prime numbers are called composite numbers.
Are any two prime numbers relatively prime?
Any two prime numbers will be relatively prime. Numbers are relatively prime if they do not have any prime factors in common. Prime numbers have only themselves as prime factors, so all prime numbers are relatively prime to the others.
Why are prime numbers divisible?
Prime numbers are divisible because any numbers that are divisible are prime. If a number isn't divisible, it isn't prime. Prime numbers have to be divisible by at least one pair of numbers to be prime.
Are there infinitely many natural numbers that are not prime?
This can be an extension to the proof that there are infinitely many prime numbers. If there are infinitely many prime numbers, then there are also infinitely many PRODUCTS of prime numbers. Those numbers that are the product of 2 or more prime numbers are not prime numbers.
Does prime factorization of composite numbers include prime and composite numbers?
No, prime factorizations consist entirely of prime numbers.
What 2 prime numbers 30?
No two prime numbers can make 30.No two prime numbers can make 30.No two prime numbers can make 30.No two prime numbers can make 30.

Are co-prime numbers and twin prime numbers the same?
No - co-prime numbers are pairs of numbers which share no positive integer factors apart from 1. Twin prime numbers are a pair of prime numbers with a difference of 2.
Do all prime numbers have prime factorization?
There is no need to do prime factorization as prime numbers are already prime.
