In this tutorial, we are going to learn about how to check if a number is divisible by another number in Python with the help of examples.

Consider, we have the following number:

To find if an above number `10`

is divisible by another number, we should divide the first number by second and get the remainder 0 then only we call it’s a divisible of another number otherwise it is not a divisible.

For example: 10%5 = 0

## Using % Modulo operator

To check if a number is divisible by another number, we can use the `%`

modulo operator in Python.

The module `%`

operator returns the remainder of two numbers `100 % 10 = 0`

so if we get a remainder `0`

then the given number is a divisible of another number otherwise it is not a divisible.

Here is an example:

```
if 10 % 5 == 0 :
print("10 is divisible by 5")
else:
print("10 is not divisible by 5")
```

Output:

In the above code we have added `10 % 5 == 0`

in if condition, so 10 is divided by 5 and returns the remainder 0 then it prints the output “10 is divisible by 5”.

Example 2:

```
if 20 % 4 == 0 :
print("20 is divisible by 4")
else:
print("20 is not divisible by 4")
```

Output:

## Checking if a number is not divisible by another

To check if a number is not divisible by another number, we can use the modulo operator `%`

but the remainder of first number by second number is not equal to 0.

Here is an example:

```
if (23 % 10 != 0):
print ("23 is not divisible by 10")
```

In the above code, 23 is divided by 10 and returns the remainder 3. So the given number is not divisible by 10.
