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.
To identify whether a number is prime or composite, look at its factors. A prime number has exactly two factors: one and itself. A composite number has more factors and can be written as the product of prime numbers. For example: Factors of 17: 1 and 17 so 17 is prime. Factors of 102: 1, 2, 3, 6, 17, 34, 51 and 102 so 102 is composite. It can be expressed as the product of prime numbers by prime factoring: 2 x 3 x 17
Now.... That depends on whether it is a number orr not!? :)
A number can be factored to determine whether it is prime or composite. A prime number has exactly 2 factors, 1 and the number itself. A composite number has more than two factors.
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 cannot. If a number is even - other than 2 - then it is a composite number. However, if it is odd, it is not easily possible to tell whether it is prime or composite.
Identify each number as prime, composite or neither: 1

13 and 19 are prime. 33 and 45 are composite.
119 is a prime 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.
