Prime Factorization of 27
Find the prime factorization of 27. Express 27 as a product of prime numbers.
Answer:
27 = 3^3
Step-by-Step Solution
Step 1
Understand Prime Factorization
To find the prime factorization of 27, 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
Check Divisibility by 2
27 is an odd number, so it is not divisible by 2.
We move on to check the next prime number: 3.
Step 3
Divide by 3
3 is a prime number that divides our current value. We can divide by 3 3 times:
27 ÷ 3 = 9
9 ÷ 3 = 3
3 ÷ 3 = 1
After dividing by 3, we have 1 remaining.
Step 4
Write the Prime Factorization
Now we combine all the prime factors we found:
Expanded form: 27 = 3 × 3 × 3
Exponential form: 27 = 3^3
We can verify: 3 × 3 × 3 = 27 ✓
