Check this by long division method.

- `4`
- `4`
- `5`

The answer is "`4`"

Even numbers are divisible by `2`. To check for divisibility by `2`, only the digit in the units place is checked.

**Test for Divisibility by `2`** : If the digit in the units place is even, then the number is divisible by `2`.

Is `218` divisible by `2`?

- Yes
- Yes
- No

The answer is "Yes". Checking the digit in units place `8`, it is concluded that the number is even and so divisible by `2`.

Is `23` divisible by `2`?

- Yes
- No
- No

The answer is "No". Checking the digit in units place `3`, it is concluded that the number is odd and so NOT divisible by `2`.
