By looking at its factor patterns.
A prime number has two factors. A composite number has more than two factors.Since 0 has no factors, it is neither prime nor composite.
54 is a composite number because it has more than 2 factors
All numbers have factors. Some factors are prime numbers, some are composite numbers, one is neither. The factors of 12 are 1, 2, 3, 4, 6, 12 Since 4, 6 and 12 are composite numbers, they are the composite factors of 12.
Zero is neither (anyone can type a random answer you know) But zero is neither prime nor composite
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. 2.9 is neither.
Prime numbers have two factors. Composite numbers have more than two. Numbers with less than two are neither.
Prime numbers have two factors; composite numbers have more than two factors. 1 and 0 are neither.
Prime numbers have two factors. Composite have more than two. Neither (one and zero) have less than two.
Start looking for factors; you already know that 1 is a factor, and that the number itself is a second factor (unless the number is 1). As soon as you find a factor that is neither 1 nor the number itself, the number is composite. If you find exactly two factors, the number is prime. If the number has only one factor, the number is 1, which is neither prime nor composite.
A prime number has two factors. A composite number has more than two factors.Since 0 has no factors, it is neither prime nor composite.
Factors can be prime or composite. The factors of 30 are 1,2,3,5,6,10,15 and 30. Of these, 3 and 5 are prime. The rest are composite except for 1, which is neither.
Factor them. Prime numbers have two factors, composite numbers have more than two.
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.
Composite. Its prime factors are 2×2×7.
It is composite because it has more than two factors
composite; 2 and 4 are its factors
1155 is a composite number because it has more than two factors.
