27 = 3³
It is not a prime, because it has factors besides 1 and 27 (namely, 3 and 9). 27 is called a "cube" though.

There is the factor tree. what you mean by prime factorization, i have no clue and no, 27 is not a prime number.
a prime number is a number which is only divisible by 1 and itself. the number 27 is divisible by 1,3,9, and 27. This property makes 27 a composite number which is simply a number with more than 2 factors.

Even numbers are not prime, except 2. Numbers ending in 5 are not prime, except 5. If the sum of the digits is divisible by 3, the number is divisible by 3. Every composite number (non-prime) has at least one factor less than (or equal to) to the square root of the number.

Keep dividing by 3. You will find 27 = 3³.
27 is not prime because it is divisible by 3.

Hi!
27 is not a prime number.
It's prime factorization is: 3*3*3
(27/3=9 9/3=3 3/3=1)
Goodluck!

the prime factorization is 3 to the third power and its a composite number beacause 27 divided by 3 is 9.

A prime number cannot be divided by anything but itself and 1. Can 27 be divided by anything else? And if so, can those numbers be divided by anything else?
