This document outlines divisibility rules to determine factors of numbers based on their digits. The rules are: if the ones digit is even, the number is divisible by 2; if the sum of the digits is divisible by 3, the number is divisible by 3; if the number ends in 0 or 5, it is divisible by 5; if the sum of the digits is divisible by 9, the number is divisible by 9; and if a number ends in 0, it is divisible by 10. Examples are provided for each rule.

1. Divisibility Rules

2. If the ones digit is divisible by 2, then 2 is a factor of the number.Examples:418241121806

3. If the sum of the number’s digits is divisible by 3, then 3 is a factor of the number.Examples:618241329612

4. If the number ends in a 0 or a 5, then 5 is a factor of the number.Examples:1085251407625

5. If the sum of the digits is divisible by 9, then 9 is a factor of the number.Examples:1881271444545

6. If the number ends in 0, then 10 is a factor of the number.Examples:20100301605860
