Answer for screen readers
The prime factors of 32 are $2^5$.
Steps to Solve
-
Identify the number to factor We are factoring the number 32.
-
Start dividing by the smallest prime The smallest prime number is 2. We divide 32 by 2:
$$ 32 \div 2 = 16 $$
- Continue dividing by the same prime We continue dividing by 2 since it divides evenly:
$$ 16 \div 2 = 8 $$
- Keep dividing by the same prime We keep dividing by 2:
$$ 8 \div 2 = 4 $$
- One more division by the same prime Continue with 2:
$$ 4 \div 2 = 2 $$
- Final division by the same prime Finish by dividing 2 by 2:
$$ 2 \div 2 = 1 $$
- List the prime factors Since we repeatedly divided by 2, we find the prime factorization is:
$$ 32 = 2 \times 2 \times 2 \times 2 \times 2 $$
This can also be expressed as:
$$ 32 = 2^5 $$
The prime factors of 32 are $2^5$.
More Information
The number 32 is a power of 2, which is significant in various areas of mathematics and computer science, especially in binary systems.
Tips
- One common mistake is attempting to use prime numbers larger than 2 too early, as 32 is even and should first be divided by 2.
- Another mistake is not recognizing that multiple factors can be the same; for example, $2$ is used multiple times in this factorization.
