Yes, a number is divisible by 2 if its last digit is even or zero.
According to the reference provided, a natural number is divisible by 2 if and only if its last digit is even. This means the last digit can be 0, 2, 4, 6, or 8. The reference gives an example of 716, which is divisible by 2 because its last digit, 6, is even.
Here's a breakdown:
- Divisibility Rule for 2: A number is divisible by 2 if its last digit is an even number or zero.
- Even Digits: Even digits are 0, 2, 4, 6, and 8.
- Examples:
- Numbers like 10, 22, 34, 46, and 58 are all divisible by 2 because their last digits are even or zero.
- Numbers like 13, 25, 37 and 49 are not divisible by 2 as their last digits are odd.
To summarize, the rule of divisibility by 2 is quite straightforward. If you check the last digit of any number and that digit is even (0, 2, 4, 6, or 8), the entire number can be divided evenly by 2 without any remainders.
