### Finding ODD & EVEN factors of any Number?

#### What is Odd number?

Odd numbers are the opposite of even numbers. They are not multiples of two and therefore cannot be evenly divided by two or any even number.

For example: 4 is an EVEN number as we get remainder "0" when divide it by "2"

For example: 5 is an ODD number as we get remainder "1" when divide it by "2"

Since odd and even numbers are defined only in reference to the set of integers (..., -3, -2, -1, 0, 1, 2, 3, ...), all negative numbers can also be either odd or even.To find the set of odd natural numbers, we use 2N+1 where N is any natural number.

Example: 7 x 9 = 63

## Key three important points to Remember:

EVEN x EVEN = EVEN

ODD x ODD = ODD

ODD x EVEN = EVEN
