Even Prime Numbers

In the previous post we have discussed about adding decimals and In today's session we are going to discuss about Even Prime Numbers. A number which is divided by itself and one only that number is known as prime number, prime numbers doesn’t generate any remainder on division by 2. So by the definition we can say that only 2 numbers is the even prime number and rest all are the odd prime numbers. All the number except 2 is divided by 2 so it violates the definition of prime number. So rest all are not even prime numbers.
If we have some digits and the sum of all the numbers digit is multiple of 3 then we can say that the number can be divided by 3 and the number zero and 1 are not considered as the prime numbers. Except the number zero and one, all the number is either prime or a composite number. The number which is always greater than 1 and that number is not prime number is known as composite number.
When we prove the number that the number is prime or not we have to follow some of the steps:
Step1: firstly we have to divide any number by 2 if you get a whole number then the number is not a prime number and if you don’t get a whole number then again divide the number by the prime number.
The even prime number is unique number i.e.2. Rest all are odd prime numbers. (know more about Prime number, here)
The even numbers n = 2m that number are divisible by 1, 2, m, and 2m.
Now we see some of the examples for finding the prime numbers.
For example: check whether the number 5, 7, 14, 17, 21, 31 are prime or not?
Solution: we know that the numbers which are divisible by 1 and itself is known as prime numbers.
So the number 5, 7, 17, and 31 are divisible by 1 and itself. So these numbers are prime numbers. Rests all the number is divisible by 2. So these numbers are not prime numbers.
Multiple regressions are used to know about the correlation between the dependent and independent variables. CBSE computer science syllabus covers all technical papers and issues that help the students for their growth.
