Prime Factorization of 74

Find the prime factorization of 74. Express 74 as a product of prime numbers.

Prime factorization of
Answer: 74 = 2 × 37
Step-by-Step Solution
Step 1 Understand Prime Factorization

To find the prime factorization of 74, 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 74 is even, we start by dividing by 2. We can divide by 2 once:


74 ÷ 2 = 37

After dividing by 2, we have 37 remaining.

Step 3 Final Prime Factor

We are left with 37, which is greater than 1.

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

Therefore, 37 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: 74 = 2 × 37


Exponential form: 74 = 2 × 37


We can verify: 2 × 37 = 74 ✓
