Prime Factorization of 44

Find the prime factorization of 44. Express 44 as a product of prime numbers.

Prime factorization of
Answer: 44 = 2^2 × 11
Step-by-Step Solution
Step 1 Understand Prime Factorization

To find the prime factorization of 44, 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 44 is even, we start by dividing by 2. We can divide by 2 twice:


44 ÷ 2 = 22
22 ÷ 2 = 11

After dividing by 2, we have 11 remaining.

Step 3 Final Prime Factor

We are left with 11, which is greater than 1.

11 cannot be divided by any prime smaller than its square root.

Therefore, 11 is itself a prime number and is our final factor.

Step 4 Write the Prime Factorization

Now we combine all the prime factors we found:


Expanded form: 44 = 2 × 2 × 11


Exponential form: 44 = 2^2 × 11


We can verify: 2 × 2 × 11 = 44 ✓
