The prime factorization is 3.
Steps:
1. Break 54 into 2 parts, I broke them into 2 and 27.
2. Since 2 is prime, leave it as is and break 27 into 2. I got 3 and 9.
3. 3 is prime so leave it alone. Break 9 into 3 and get 3 and 3. Your prime factor is 3.
Now, you need the prime factorization, which, if I remember correctly, is the prime factors that you left and did not break apart. List these in order from least to greatest. Your prime factorization should end up looking like this:
2 x 3 x 3 = 54
