5 5 1 3 3 6 2 4 4
The first 5 is red and is a factor of 5 next to it.
The 1 is a factor of both 5 & 3
The 3 is a factor of both 3 & 6
The 2 is a factor of both 6 & 4
The 4 is a factor of 4
The way I found my solution was I tried to get rid of the bigger numbers as they can only be factors of themselves so they are not very helpful. In my solution, I put the same numbers together as they can be factors of themselves and I used 1 with the bigger numbers.
