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.

2 squared 1 = 4 so the divisibility rule is that it is divisible by 1, 2 and 4.
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.
the number is even.
Every number that ends in 0 is a multiple of both 5 and 10. Multiples of 5 always end in 0 or 5 and multiples of 10 always end in 0. 0 is the only common last digit
