## How to find the divisibility of numbers

First, look at the last number and see if it's even or odd, that's how you'll know if the divisibility of the number is even or odd. Then you see what multiples fit into that number, or you can divide the number in your head and see if it equals amount.

## What divisibility is

Divisibility is the number you can divide by something to get an equal number. For example; 345 the 5 is what you want to look at. 5 is divisible by 1 and 5. So 1 and 5 are the divisibility numbers.

## Divisibility Rules

2:Last digit is even
3:Digit is sum to multiple of 3
4:Last two digits are a multiple of 4
5:Last digit is 0 or 5
6:Divisible by 2 and 3
9:Digits sum to a multiple of 9
10: Last digit is a 0

Examples: 1.6386 is divisible buy 2,3,and 6. You can't divide it by 4,5,9,and ten because they don't fall under that category. 2.4682 is divisible by 2 and 4. 5,363 is divisible by 3 and 9.
