Determine All Factors of the Number 18

To solve this problem, we'll use prime factorization:

• Step 1: Begin by dividing 18 by 2, the smallest prime number. $18 \div 2 = 9$. Therefore, 2 is a factor.

• Step 2: Now factor 9, which is the result from the previous division. The smallest prime factor of 9 is 3, since $9 \div 3 = 3$. Thus, 3 is a factor.

• Step 3: Continue with the result from step 2. Divide 3 by 3 (since $3 \div 3 = 1$). Another 3 is a factor.

• Step 4: The final division of 1 means we have completely factorized the number.

In conclusion, the prime factors of 18 are $2, 3, 3$. Our factorization shows that the correct answer choice corresponds to: $2, 3, 3$.
