Prime Factorization of 16

Find the prime factorization of 16. Express 16 as a product of prime numbers.

Prime factorization of
Answer: 16 = 2^4
Step-by-Step Solution
Step 1 Understand Prime Factorization

To find the prime factorization of 16, 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 16 is even, we start by dividing by 2. We can divide by 2 4 times:


16 ÷ 2 = 8
8 ÷ 2 = 4
4 ÷ 2 = 2
2 ÷ 2 = 1

After dividing by 2, we have 1 remaining.

Step 3 Write the Prime Factorization

Now we combine all the prime factors we found:


Expanded form: 16 = 2 × 2 × 2 × 2


Exponential form: 16 = 2^4


We can verify: 2 × 2 × 2 × 2 = 16 ✓
