Is 27 prime or composite

Answer 1

27 is 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.
27 is a composite number because it has more than two factors

Answer 2

Composite, for it has four positive integer divisors, 1, 3, 9, 27. To be a prime number, it needs to have only two integer divisors, 1 and itself.

A prime number is a number with only two factors: 1 (also known as unity) and itself. A composite number is a number with more than two factors; in other words, it has at least one factor besides 1 and itself. 27 has factors other than 1 and itself, so it is not a prime number. For example, it is divisible by 3. (You can check this by adding the digits of the number: 2 + 7 = 9. If the sum of the digits is divisible by 3, the number is also divisible by 3.) Therefore, 27 is a composite number.

It is the product of a set of numbers (n, m) such that

nm = x; where 1 < n <= floor(sqrt(x)) and m <= x/2
27 is composite
27 is a composite number because it is a multiple of 3.
It's divisible by 1, 3, 9, and 27. Thus, it's composite. Only integers below two are neither prime nor composite. The rest are one or the other.
27 is composite
27 is composite number as it is divisible by 1, 3, 9, 27.
27 is composite number as it is divisible by 1, 3, 9, 27.

Answer 3

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. 27 is composite.
