Prime Factorization of 110

Find the prime factorization of 110. Express 110 as a product of prime numbers.

Prime factorization of
Answer: 110 = 2 × 5 × 11
Step-by-Step Solution
Step 1 Understand Prime Factorization

To find the prime factorization of 110, 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 110 is even, we start by dividing by 2. We can divide by 2 once:


110 ÷ 2 = 55

After dividing by 2, we have 55 remaining.

Step 3 Divide by 5

5 is a prime number that divides our current value. We can divide by 5 once:


55 ÷ 5 = 11

After dividing by 5, we have 11 remaining.

Step 4 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 5 Write the Prime Factorization

Now we combine all the prime factors we found:


Expanded form: 110 = 2 × 5 × 11


Exponential form: 110 = 2 × 5 × 11


We can verify: 2 × 5 × 11 = 110 ✓
