Answer:
Step-by-step explanation:
We find what number we multiply by another number to get 54, 24, 18
54: 1, 2, 3, 6, 9, 18, 27, 54
24: 1, 2, 3, 4, 6, 8, 12, 24
18: 1, 2, 3, 6, 9, 18
Now the numbers that repeat in these sets are the common factors
We got 1, 2, 3, and 6, which make these our common factors
