Final answer:
Irene is not correct; the true factors of 88 are 1, 2, 4, 8, 11, 22, 44, and 88. Numbers such as 24, 81, and 20 are not factors of 88.
Step-by-step explanation:
Irene wants to list the factors of 88 but her list contains errors. The correct factors of 88 are 1, 2, 4, 8, 11, 22, 44, and 88. The process of finding these factors involves identifying all the whole numbers that divide 88 without leaving a remainder. The number 24 is not a factor of 88 because when 88 is divided by 24, it leaves a remainder. Similarly, the numbers 81 and 20 are not factors of 88 for the same reason; none of them divide 88 evenly. Therefore, Irene's factorization list of 88 should have only included the numbers 1, 2, 4, 8, 11, 22, 44, and 88, and should have excluded 24, 81, and 20.
