Find All Factors of 12: A Comprehensive Guide

To find all the factors of 12, we will perform a prime factorization:

• Start with the smallest prime number, 2. Since 12 is divisible by 2, we divide 12 by 2:
• $12 \div 2 = 6$
• Next, we have 6, which is also divisible by 2:
• $6 \div 2 = 3$
• Now we are left with 3, which is a prime number and divisible by itself:
• $3 \div 3 = 1$

Since we reached 1, the division process stops.

Therefore, the prime factors of 12 are $2, 2,$ and $3$.

Expressing 12 using these factors: $12 = 2 \times 2 \times 3$.

Thus, the correct list of factors is given by choice 2: $3, 2, 2$.
