Divisibility Rule For 2 With Examples
How to Solve divisible By 2
The divisibility rule for 2 states that a number is divisible by 2 if its last digit is even. The even digits are 0, 2, 4, 6, and 8. This rule is very straightforward and can be applied to both whole numbers and integers.
Steps to Apply the Rule:
- Identify the Last Digit: Look at the last digit of the number.
- Check for Evenness: Determine if that last digit is one of the even digits (0, 2, 4, 6, or 8).
- Conclusion:
- If the last digit is even, the number is divisible by 2.
- If the last digit is odd (1, 3, 5, 7, 9), the number is not divisible by 2.
Examples:
- Example 1: 34
- Last digit: 4
- Since 4 is even, 34 is divisible by 2.
- Example 2: 57
- Last digit: 7
- Since 7 is odd, 57 is not divisible by 2.
- Example 3: 1024
- Last digit: 4
- Since 4 is even, 1024 is divisible by 2.
- Example 4: 99
- Last digit: 9
- Since 9 is odd, 99 is not divisible by 2.
- Example 5: 0
- Last digit: 0
- Since 0 is even, 0 is divisible by 2.
Summary:
The divisibility rule for 2 is simple and effective:
just check the last digit of the number. If it’s even, the whole number is divisible by 2. This rule is particularly useful for quickly determining divisibility without performing division.
