40 is wholly divisible by 1,2,4,5,& 8
With regards to digit patterns
1 intersects with all digits the maximal amount of times, followed by 2 intersecting with half of the digits the maximum amount of times.
3 intersects with all digits, but every 3 counts.
4 half digs on 4 counts, 5 2 digs on 5 counts, 6 half digs 6 counts, 7 all digs 7 counts, 8, half digs 8 counts, 9 all digs 9 counts. As to what this implies about the behavior of the digits I don't know, but with regards to prime numbers, they come in 2 flavors, even composites and prime composites.
