How to Have a Good Command on Prime Numbers?

Prime numbers are the positive integers that will have only two factors which will be the number one and the integer itself. One can also say that they are the numbers that are only divisible by one or the number itself. Another way of defining the prime number is that it can be termed as the positive number or integer which is not a product of any two other positive integers.

There is no such specific formula for defining the prime number apart from being clear about the process of finding the factors.

 Any number which does not follow this particular trend of the number itself and one as the factor can be termed as the composite number which will make sure that they can be further factored into other kinds of positivity just as well.

Prime number was discovered in the year 275-194BC Greece and this was based upon the concept of finding out the prime number from a list of natural numbers and draining out the composite numbers very easily. Students can also go with the option of practicing this particular method to become masters of the concept of prime number very easily.

Being clear about the list associated with prime number from numbers one-hundred is very important for the kids so that they can deal with the concept of actors and prime factorization very easily and never have to face any hassle throughout the process.

Following are some of the basic points associated with the prime numbers:

  • Even prime number: The prime number are the numbers that have only two factors and the numbers that are evenly divisible by two will be the even numbers. Hence, a number that satisfies this particular condition is the number two itself because the rest of the prime number are odd and are known as the odd prime number.
  • Twin prime numbers: The prime number which have only one composite number between both of them are known as the twin prime number. Another definition of the twin prime number is the pair of prime number that differ by two only. The examples can be five and seven, 11 and 13, 59 and 61 and several other kinds of things.
  • Co-prime number: The pair of numbers that have only one factor in common between both of them are known as the co-prime number because the prime factors of the co-prime number are not the same. 6 and 13 are co-prime and the common factor between both of them is the one only.
  • The prime number chart: Before the introduction of the concept of calculators and computers the numerical tables were the only source of recording the prime number and dealing with the concept of prime factorisation very easily.

This is considered one of the most effective methods of finding out the prime number up to a hundred which will be represented into the colored boxes and the rest of them will be normal. Hence, being clear about this particular concept is important for the kids. 

Following are the basic properties of the prime numbers:

  • Every number is greater than one that can be divided by at least one prime number.
  • Every even positive integer greater than two can be perfectly expressed as the sum of two primes
  • Except two all the other prime numbers are odd and in other words, one can say that two numbers are the only even prime number.
  • Two prime number are always co-prime to each other.
  • Each composite number can be factored into prime factors and individually everybody will be unique.

 Hence, being clear about all the above-mentioned properties is very much important. Further, the kids need to register themselves on platforms like Cuemath so that they have a good command over the prime numbers 1 to 100 and are very much successful in solving the questions to score well in exams.
