>>I need to create algorithm (based on an integer number) that by applying some formula or equation to this number I can identify if the number belongs to group 1, 2, or 3 or any combination of them (e.g. 1 and 2, 1 and 3, 1 and 2 and 3, 2 and 3)
>>For example, number 8 would indicate belonging to all three groups (since I can divide this number by the group number without a remainder.

Is this about your options ? (from yesterday)
Then the groups are just bits. Test witth BitTest()
And belonging to all three groups = 7
