Is 27 a composite number or a prime number?

Answer 1

A Prime number is a number with two and 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.

No, 27 is not prime because 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

Answer 2

27 is a composite number. This is because composite numbers are any number that has more than two factors(one and itself). Therefore, since 3 and 9 are also factors of 27 that makes it a composite number.

Answer 3

27 is composite, because 3 x 9 = 27.

Answer 4

27 is a composite number because it has at least one positive factor other than one or itself.

Answer 5

It is a composite number because it has more than two factors

Answer 6

It is a composite number.
