The divisibility rule of 3 is that you add the digits together and then if the number you come up with is divisible by 3, then the number itself is divisible by 3. In this instance, 5 + 8 + 5 = 18/3 = 6, therefore, 585 is divisible by 3.
If the number ends in 5 or 0 the whole number is divisible by 5.
if the number ends on 5 or 0 the number is divisible by 5

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
The rule is: if a number is divisible by 5 and 17 at the same time, that number is divisible by 85
If the rules for 2 and 3 work, the number is divisibale by 5.
If a number ends with 0, it is divisible by 10. If a number ends with 5 or 0, it is divisible by 5.
