Prime and Composite Numbers

Home Numbers & Operations Prime and Composite Numbers Prime and Composite Numbers Worksheets Here are more than 25 prime and composite number worksheets, carefully designed for grade 4 through grade 6 students. We will clearly discuss the concepts of prime, composite, co-prime, and twin prime numbers. We can classify all natural numbers as prime and composite. Prime Numbers: Any natural number that has only two factors, the number itself and 1 is known as a prime number. Eg. 1, 2, 3, 5,……11,……23,…..97,… The number 3 has only two factors. That is, it is only divisible by 3 and 1. (Without leaving a remainder). Thus 3 is a prime number. The number 2 is the smallest prime number. Interestingly, its the only even prime number which means all other prime numbers are odd.   Composite Numbers: Any natural number that can be divided by other natural numbers and with the number itself and 1 is a composite number. Eg. 6, 8, 9,…..86,…99,… With 1 and 6, the number 6 has other factors like 2 and 3. Thus the factors of 6 are 1, 2, 3, and 6 which makes 6 a composite number. 1 is the only number which is neither prime nor composite. Twin primes: Prime number pairs which differ from each other by 2 are twin primes. Eg. 3 and 5, 11 and 13, 41 and 43….. In the above shown pair of numbers, the difference between the numbers is 2. Co-primes: Numbers that do not have any common factor other than 1 are called co-prime numbers. Eg. Number pairs 2 and 3, 3 and 4, 4 and 5…………17 and 23, 29 and 31,…….. 29 and 31 are both twin primes and co-primes. All twin primes are prime numbers, whereas all co-primes need not be prime numbers.

Squares and Cubes of Numbers

Home Numbers and Operations Squares and Cubes of Numbers Squares and Cubes of Numbers worksheets Squares and cubes of numbers are an easy concept which involves the basic multiplication operation throughout. All natural numbers can be squared and cubed. Squares and cubes always follow a pattern. Look at the figures shown below. Look at the pattern of dots arranged in the figures shown above. They are arranged in square shape and can be called perfect squares. Thus the number obtained by multiplying a number by itself is a square number. The first 5 square numbers are calculated as follows: 1 x 1= 1 2 x 2= 4 3 x 3 =9 4 x 4= 16 5 x 5= 25 Cube Numbers: A perfect cube is obtained when a number is multiplied by itself, three times. Thus, when we calculate the cube root of numbers, we always get a natural number which also means all natural numbers can be cubed. The first 5 cube numbers are calculated as follows: 1 x 1 x 1= 1 2 x 2 x 2= 8 3 x 3 x 3= 27 4 x 4 x 4= 64 5 x 5 x 5= 125 Print these worksheets to know more about perfect squares and perfect cubes.

Divisibility Rules

Divisibility Rules Worksheets

Home Numbers and Operations Divisibility Rules Free Printable Divisibility Rules Worksheets Download Worksheets How do you know if a large number is divisible by 2? This is simple. You just need to check the last number. If the last number is even or 0 then it’s divisible by 2. Example: 322, 514, 846, 978, 20. Similarly there are different rules for other numbers. We will learn all divisibility rules from 3 to 12 and apply them in these worksheets. Follow the table carefully. Number Divisibility Rule 3 A number is divisible by 3 if the sum of its digits is divisible by 3 4 If the last two digits are divisible by 4, then the given number is divisible by 4 5 A number is divisible by 5 if it’s last number is 0 or 5 6 If a number is divisible by both 2 and 3, then the number is divisible by 6 7 If the difference between twice the last number and the other digits of the number is divisible by 7, then the number is divisible by 7 8 A number is divisible by 8, if the last three digits of the number is divisible by 8 10 Any number whose last digit ends with a zero is divisible by 10. 11 From the given number, separate the digits in odd places and even places. Sum up the digits of different groups. Find the difference. If the resultant number is divisible by 11, the given number is divisible by 11. You have other small tricks for odd numbers and even numbers. Check the chart given below for detailed explanations. Detailed examples for all the numbers are given in the charts shown below. You can print and paste them for reference. Pick a few numbers and apply these rules to check if they are divisible by numbers 2 to 12 with the help of the examples. Worksheets here emphasize the same concept. You will also get to know the factors of numbers when you work on these pages. Download them all. Divisibility Rules worksheets free download pdf
