By tautology. If it did not work, it would not be a divisibility rule!
If a number ends in 0, it is divisible by 10.
What is the divisblity rule by 8

If a number ends with 0, it is divisible by 10. If a number ends with 5 or 0, it is divisible by 5.
Judging by some of the questions asked on this site, the first rule is that divisibility is a concept that applies only to whole numbers.
2 squared 1 = 4 so the divisibility rule is that it is divisible by 1, 2 and 4.
