The set A = {1, 2, 4, 8} can be correctly associated with which description?
Answer and explanation
Correct answer: Positive factors of 8
The governing concept is factor identification. A positive factor of 8 divides 8 exactly, leaving remainder zero. Checking the listed values, 8 ÷ 1 = 8, 8 ÷ 2 = 4, 8 ÷ 4 = 2, and 8 ÷ 8 = 1. These are all the positive factors of 8. Multiples of 8 continue as 8, 16, 24, and so on, so option A is correct.
