In this tutorial, you will learn two different ways to reverse a number in Kotlin with program examples.

### Method 1: Using reversed() & String

```
fun main() {
var num = 13436
var str = num.toString()
var reversedString = str.reversed()
num = reversedString.toInt()
print(num)
}
```

In this method, we are first converting the integer number to a string. Then reversing the string using reversed() function. Finally converting the reversed string back to an integer.

### Method 2: Using Loop, Modulo, and Division

```
fun main() {
var num = 13436
var reversedNum = 0
while (num != 0) {
reversedNum = reversedNum * 10 + (num % 10)
num /= 10
}
print(reversedNum)
}
```

In this method, we used a while loop to extract each digit of the number by using the modulo operator (%) to get the remainder when divided by 10, and then the division operator (/) to remove the last digit. The extracted digits are then used to make the reversed number.
