A factor is a number that divides 12 completely. The chapter says 1 and the number itself are always factors, and 12 can also be divided exactly by 2, 3, and 4. So the factors of 12 from the options are 1, 2, 3, and 4.

12, 18, 24, 30

Step 1: Check if each number is divisible by 6. Step 2: 12 ÷ 6 = 2 ✓, 18 ÷ 6 = 3 ✓, 20 ÷ 6 = 3.33... ✗, 24 ÷ 6 = 4 ✓, 30 ÷ 6 = 5 ✓. Step 3: Multiples of 6 are 12, 18, 24, and 30.

1, 2, 4

Step 1: Find factors of 8: 1, 2, 4, 8. Step 2: Find factors of 12: 1, 2, 3, 4, 6, 12. Step 3: Common factors are numbers in both lists: 1, 2, and 4.

18

Step 1: Multiples of 6: 6, 12, 18, 24, 30... Step 2: Multiples of 9: 9, 18, 27, 36... Step 3: First common multiple is 18, so both animals first meet at position 18.
