What is the prime factorization of 20? Choices: (A)2 × 2 × 5 (B)2 × 2 × 2 × 5 (C)4 × 5 × 5 (D)2 × 10

Determine Prime Number: Step 1: Determine if 20 is a prime number. Since 20 can be divided by numbers other than 1 and itself, it is not a prime number. Divide by 2: Step 2: Start dividing 20 by the smallest prime number, which is 2. 20 ÷ 2 = 10. Continue Dividing by 2: Step 3: Continue dividing the quotient by 2. 10 ÷ 2 = 5. Divide by 5: Step 4: Now, divide the new quotient by the next smallest prime number. 5 ÷ 5 = 1. Since we reached 1, we stop here.
