### Grade 5 - Mathematics1.12 Numbers - Prime, Composite, Odd, Even, Multiple, Factors

 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......... Directions: Answer the following questions and write 10 examples of each.
