Identifying All Factors of the Number 8

Write all the factors of the following number: $8$

To find the factors of 8, we'll use prime factorization.

• Step 1: Begin with the smallest prime number, 2.
• Step 2: Divide 8 by 2, which gives 4. Since 4 is even, divide by 2 again.
• Step 3: Divide 4 by 2, which gives 2. Divide 2 by 2 one more time.
• Step 4: This yields 1, so we've fully factored the number.

Thus, the prime factorization of 8 is $2 \times 2 \times 2$.

The factors of the number 8 are $2, 2, 2$.

Therefore, the correct answer is choice 4: $2, 2, 2$.
