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