54 = 2 x 3 x 3 x 3
81 = 3 x 3 x 3 x 3
common factor of 54 and 81 = 3 x 3 = 9
Answer: 9
Answer:
C) 9
Step-by-step explanation:
Note that the factors are already given to you:
54 = 2 * 3 * 3 * 3
81 = 3 * 3 * 3 * 3
Note that they all have 3 3's. However, there is not a choice for 27 (as 3 * 3 * 3 = 27), therefore, choose the next option: 3 * 3 = 9
C) 9 is your answer.
