Discover the Factors of 16: A Fundamental Math Exercise

Write all the factors of the following number: $16$

To solve this problem, we will follow the prime factorization approach:

• Step 1: Start with the smallest prime number, which is 2.
• Step 2: Divide 16 by 2 to get 8. Thus, $2 \cdot 8 = 16$.
• Step 3: Divide 8 by 2 to get 4. Thus, $2 \cdot 4 = 8$.
• Step 4: Divide 4 by 2 to get 2. Thus, $2 \cdot 2 = 4$.
• Step 5: Divide 2 by 2 to get 1. Thus, $2 \cdot 1 = 2$.

After performing all divisions, the complete list of prime factors becomes $2, 2, 2, 2$.

Therefore, the prime factors of 16 are all twos: $2, 2, 2, 2$.

Finally, based on the available choices, the correct choice is:

$2, 2, 2, 2$.
