# Using Divisibility Worksheets

How to Use Divisibility? Among the different arithmetic operations, the division is the most complicated one and cause problems for young students everywhere. However, learning how to use divisibility can help us solve problems quite effectively. The rule of divisibility deals with you to work out whether a number is divisible by another number or not. Now, if the number ends with an even number, then it will always be divisible by 2. However, it's not certain that it will be divisible by other even numbers. For instance, if you have a number 5,106, it's an even number, so it is divisible by 2. However, is it divisible by 6? For that you need add the digits separately, i.e. 5 + 1 + 0 + 6 = 12. Now, 12 is an even number and it is also divisible by 3 from which 6 can also be divided.
