Work Step by Step

A number is prime if it has only two factors: 1 and itself. We know that the factors of 27 are 1, 3, 9, and 27. 3 is a prime number, so we can divide 27 by 3 $27\div3=9$ The factors of 9 are 1, 3, and 9. Since 3 is a prime number, divide by 3. $9\div3=3$ 3 is also a prime number Therefore, the prime factorization of 27 is $3\times3\times3=3^{3}$.
