Is 27 a prime number

1 answer

No, 27 is not a prime number. A prime number is defined as a natural number greater than 1 that has no positive divisors other than 1 and itself. Since 27 can be divided evenly by 1, 3, 9, and 27, it has divisors other than 1 and itself, making it a composite number. Specifically, 27 is \(3^3\) (or \(3 \times 3 \times 3\)).
