Here are a few sequences:

20,6,4,3,2,2,2 etc.
10,4,3,2,2,2etc.
16,5,2,2,2 etc.
60,12,6,4,3,2,2etc.

Each sequence follows the exact same rule and when it says 'etc.' the last digit is repeated an infinite number of times. (The first number in each sequence is random and does not follow the rule).

What is the rule for these sequences?

that would make sense.
If look at that way using factor sequences, all the answers are true. Heck every sequence that starts with any positive number will become 2 no matter what, cept 1.
