If you divide an even number by two and the result is even, the original number is divisible by four. If the number is more than two digits, you only need to focus on the last two since all hundreds and thousands and up are divisible by four. If the number is two digits or less, you need to memorize the 4 times table.   Wiki User

Equivalently, halve the number formed by the last two digits. If the quotient is even, then the original number is divisible by 4.   Wiki User
