The first few composite numbers (sometimes called "composites" for short) are 4, 6, 8, 9, 10, 12, 14, 15, 16, ... (OEIS A002808), whose prime decompositions are summarized in the following table. Note that the number 1 is a special case which is considered to be neither composite nor prime.

50 and Multiples For example, 50 is a multiple of all these numbers: 1, 2, 5, 10, 25, and 50. And 1, 2, 5, 10, 25, and 50 are all factors of 50. 50 is a composite number. 50 = 1 x 50, 2 x 25, or 5 x 10.

Is 25 a composite number? Yes. 25 is divisible by 5, so it is composite. The factors of 25 are 1, 5, and 25.

A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself. However, 4 is composite because it is a product (2 × 2) in which both numbers are smaller than 4.

One is neither prime nor composite. To be prime, a number must have two positive divisors: the number itself and one. One only has a single positive divisor.

15 is a composite number. 15 = 1 x 15 or 3 x 5. Factors of 15: 1, 3, 5, 15.

24 is a composite number. The exponents in the prime factorization are 3 and 1. Adding one to each and multiplying we get (3 + 1)(1 + 1) = 4 x 2 = 8. Therefore 24 has exactly 8 factors.

Howe...” I believe 0, in addition to 1, is also prime. However, if you are referring specifically to natural numbers, then 1 would be the only number that is neither prime nor composite.

Prime numbers are numbers that have only 2 factors: 1 and themselves. For example, the first 5 prime numbers are 2, 3, 5, 7, and 11. By contrast, numbers with more than 2 factors are call composite numbers.

When a number has more than two factors it is called a composite number. Here are the first few prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199, etc.

Prime Factors. ... When a composite number is written as a product of all of its prime factors, we have the prime factorization of the number. For example, the number 72 can be written as a product of primes as: 72 = . The expression " " is said to be the prime factorization of 72.
267252
A composite number has more than two factors. The number 1 is neither prime nor composite. The prime numbers between 2 and 31 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29 and 31 since each of these numbers has only two factors, itself and 1.
1355257
Natural numbers that have more than two positive factors are called composite. 1 has only one positive factor i.e. no. 1 only. Hence 1 is neither prime nor composite.

Factor Tree Calculator The number 12 is a composite number because 12 can be divided by 1, by itself and at least by 2 and 3. So, it is possible to draw its prime tree. The prime factorization of 12 = 22•3.
81091
Therefore, 11 is a prime number. The number 12 can be written as the 1 x 12, 3 x 4, and 2 x 6. Since 12 is divisible by numbers other than 1 and itself, 12 is a composite number.
