Factorization Breakdown: Listing All Factors of 99

To solve this problem of finding the factors of $99$, we will apply the process of prime factorization step-by-step:

Step 1: Begin with the smallest prime number, which is $2$. Since $99$ is odd, it is not divisible by $2$. Therefore, we proceed to the next prime number, $3$.

Step 2: Check divisibility by $3$. The sum of the digits of $99$ is $9 + 9 = 18$, which is divisible by $3$, indicating that $99$ is divisible by $3$. Performing the division, we have:

$99 \div 3 = 33$

Step 3: We have $33$ now. Check for divisibility by $3$ again, as $33 \div 3 = 11$. Now, $11$ is left, which is a prime number. Therefore, we have our factors.

The prime factorization of $99$ is:

$99 = 3 \times 3 \times 11$

These numbers are the prime factors of $99$. Thus, the correct choice from the options provided is:

$11, 3, 3$.
