Even Numbers:
- The numbers that are exactly divisible by 2 are called even numbers.
- Examples: 2, 4, 6, 8, 10..........
Odd Numbers:
- The numbers that are not divisible by 2 are called odd numbers.
- Example: 1, 3, 5, 7, 9..........
Factor:
- An exact divisor of a number is called its factor.
- Example: 20 is completely divided by 5 and leaves remainder zero. Therefore 5 is a factor of 20.
Multiple:
- When the given number is multiplied by any natural number then the product is a multiple of the given number and the natural number.
- Example: When 8 is multiplied by 4 we get 32. Therefore 32 is a multiple of both 8 and 4.
Prime Numbers:
- A number larger than 1 that is completely divisible (remainder 0) by 1 and itself only is called a prime number.
- It has only 2 factors: 1 and itself.
Example: 2, 3, 5, 7, 11................
Composite Numbers:
- A number that is completely divisible (remainder 0) by any other number besides 1 and itself is called a composite number.
- It has more than two factors.
Example: 4, 6, 8, 9, 10.........
