问题 How many different positive integers are factors of 342?
选项 A、9
B、11
C、12
D、20
E、22
答案 C
解析 From the answers we can see that the list of factors will be relatively small, so it’s easiest just to list them out. The pairs of factors are 1 and 342, 2 and 171, 3 and 114, 6 and 57, 9 and 38, and 18 and 19. That makes 12 factors.
