A number is divisible by 4 if the last two digits of the number are divisible by 4.
For example, the number 1236 is divisible by 4 because the last two digits, 36, are divisible by 4. However, the number 542 is not divisible by 4 because the last two digits, 42, are not divisible by 4.
This rule is useful for quickly determining if a number is divisible by 4 without having to perform the actual division.
Here are some examples of numbers that are divisible by 4:
- 1236: The last two digits, 36, are divisible by 4.
- 2048: The last two digits, 48, are divisible by 4.
- 1000: The last two digits, 00, are divisible by 4.
Here are some examples of numbers that are not divisible by 4:
- 542: The last two digits, 42, are not divisible by 4.
- 789: The last two digits, 89, are not divisible by 4.
- 1235: The last two digits, 35, are not divisible by 4.
