Quizplus · Accepted Answer

To find the prime factorization of 110, we can start by dividing it by the smallest prime number, which is 2. 
110 ÷ 2 = 55 
We continue to divide by the smallest prime factor until we cannot divide anymore. 
55 ÷ 5 = 11 
11 is prime, so the prime factorization of 110 is 2 × 5 × 11, which is answer choice B.
