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. 19 is prime.
15 and 16 are both composite numbers
11, 13, 17, 19, 23, 29 are the primes between 10 and 30 so the composite numbers are all the others. 12,14,15,16,18,20,21,22,24,25,26,27,28, and 30 are the composite numbers between 10 and 30.
Composite. Even numbers higher than 2 are not Primes.
No primes are composite. The prime factors of 80 are 2 and 5.
That's a prime factorization.
Prime 2 3 5 7 11 13 17 19 doesn't go into it. This works because all other numbers are composite and are made up of primes
31
All composite numbers can.
No, it is composite.
Composite
They are primes.
A composite number is basically one that is NOT a prime - a composite number is a product of two or more primes.
