Best Answer

The definition of even is "divisible by 2", while odd means "not divisible by 2". You can use this definition and simply divide by 2; however, a faster way is to check the last digit of a number. If the last digit is even (0, 2, 4, 6, or 8), then the entire number is even; otherwise it is odd.
