Prime Factorization of 114

Find the prime factorization of 114. Express 114 as a product of prime numbers.

Prime factorization of
Answer: 114 = 2 × 3 × 19
Step-by-Step Solution
Step 1 Understand Prime Factorization

To find the prime factorization of 114, 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 114 is even, we start by dividing by 2. We can divide by 2 once:


114 ÷ 2 = 57

After dividing by 2, we have 57 remaining.

Step 3 Divide by 3

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


57 ÷ 3 = 19

After dividing by 3, we have 19 remaining.

Step 4 Final Prime Factor

We are left with 19, which is greater than 1.

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

Therefore, 19 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: 114 = 2 × 3 × 19


Exponential form: 114 = 2 × 3 × 19


We can verify: 2 × 3 × 19 = 114 ✓
