The factors of 18 are: 1, 2, 3, 6, 9, and 18. These factors are numbers that can be divided evenly into 18 without leaving a remainder.18 is a composite number because it has more than two factors; it has six factors. A factor is a number that divides into another number entirely (without leaving a remainder).

The prime factors of 18 are 2 and 3. 2 and 3 are prime numbers because they have no factors other than 1 and themselves. To determine the prime factorization of 18, divide 18 by its smallest prime factor (2) to obtain 9.

Then divide 9 by its smallest prime factor (3) to obtain 3. Therefore, the prime factorization of 18 is 2 × 3 × 3.
