Prime Factorization of 38
Find the prime factorization of 38. Express 38 as a product of prime numbers.
Answer:
38 = 2 × 19
Step-by-Step Solution
Step 1
Understand Prime Factorization
To find the prime factorization of 38, 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 38 is even, we start by dividing by 2. We can divide by 2 once:
38 ÷ 2 = 19
After dividing by 2, we have 19 remaining.
Step 3
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 4
Write the Prime Factorization
Now we combine all the prime factors we found:
Expanded form: 38 = 2 × 19
Exponential form: 38 = 2 × 19
We can verify: 2 × 19 = 38 ✓
