What is an Even or Odd Number?
An **even number** is divisible by 2 without a remainder, while an **odd number** leaves a remainder of 1 when divided by 2.
How to Identify Whether a Number is Even or Odd?
To identify whether a number is even or odd, divide it by 2. If the remainder is 0, it's even; otherwise, it's odd.
To identify whether a number is even or odd, follow these simple steps:
Check the Last Digit:
- If the number ends in 0, 2, 4, 6, or 8, it is even.
- If the number ends in 1, 3, 5, 7, or 9, it is odd.
Divide by 2:
- If a number is divisible by 2 without a remainder, it is even.
- If dividing the number by 2 leaves a remainder of 1, it is odd.
Examples:
Check if 12 is even or odd
Step 1: Check if 12 ends in an even digit. The last digit is 2, so it’s even.
Step 2: Divide 12 ÷ 2 = 6. There is no remainder, so 12 is an even number.
Check if 15 is even or odd
Step 1: Check if 15 ends in an odd digit. The last digit is 5, so it’s odd.
Step 2: Divide 15 ÷ 2 = 7 with a remainder of 1, so 15 is an odd number.
Even or Odd Number Formula
Even numbers satisfy \( n \% 2 = 0 \), while odd numbers satisfy \( n \% 2 \neq 0 \), where \( n \) is the number.
