Hello,

I'm not sure that I understand your problem correctly. I assume that you want to know"What is the maximum number of pairs where one number is amultipleof the other number?"

If so:

1: each other number is a multiple of 1, thus you get 8 pairs

2: multiples(4, 6, 8) thus 3 pairs

3: multiples (6, 9), thus 2 pairs

4: multiple (8), thus 1 pair

Therefore I got 14 pairs
