Prime Factorization of 54

Find the prime factorization of 54. Express 54 as a product of prime numbers.

Prime factorization of
Answer: 54 = 2 × 3^3
Step-by-Step Solution
Step 1 Understand Prime Factorization

To find the prime factorization of 54, we need to express it as a product of prime numbers.


We do this by repeatedly dividing by the smallest prime that divides evenly, starting with 2.

A prime number is only divisible by 1 and itself (2, 3, 5, 7, 11, 13, ...).

Step 2 Divide by 2

Since 54 is even, we start by dividing by 2. We can divide by 2 once:


54 ÷ 2 = 27

After dividing by 2, we have 27 remaining.

Step 3 Divide by 3

3 is a prime number that divides our current value. We can divide by 3 3 times:


27 ÷ 3 = 9
9 ÷ 3 = 3
3 ÷ 3 = 1

After dividing by 3, we have 1 remaining.

Step 4 Write the Prime Factorization

Now we combine all the prime factors we found:


Expanded form: 54 = 2 × 3 × 3 × 3


Exponential form: 54 = 2 × 3^3


We can verify: 2 × 3 × 3 × 3 = 54 ✓
