**Divisibility Rules**

In this topic, you must list all of the factors of a number. To succeed, you must be good at your divisibility rules.

Here are some divisibility rules that should help:Divisibility by 2:If the number ends in 0,2,4,6, or 8, it is divisible by 2.Divisibility by 3:If the sum of the digits is divisible by 3, the number is divisible by 3. Example: 27 is divisible by 3 because 2 + 7 = 9, which is divisible by 3.Divisibility by 4:If the last two digits are divisible by 4.Divisibility by 5:If the number ends in 0 or 5, it is divisible by 5.Divisibility by 6:If the number is divisible by 2 and 3.Divisibility by 9:If the sum of the digits is divisible by 9.Divisibility by 10:If the last digit is 0.Example: Factor 18: Everything is divisible by 1, giving us the factors 1 and 18 18 is divisible by 2, giving us 2 and 9 18 is divisible by 3, giving us 3 and 6 Answer: 1 2 3 6 9 18
