How to Recognize Prime Numbers?
If we talk about math’s what comes first in our mind. And of course, the answer is numbers. Here we talk about Prime Numbers. And we discuss the prime numbers in detail. First, let us talk about what numbers are. Numbers are the which helps us in measuring some quantity, Numbers the one which helps in counting objects, so basically we can say that numbers tell us the exact quantity of anything. Without numbers, we can not calculate anything. Numbers are the ones that help in every basic mathematical problem like without numbers how can we add, subtract, multiply or divide.
What do clicks in your mind when we say Prime Number? First, comes that it’s a part of mathematics, second that we had learned about it in primary school. The commonly used prime numbers 2,3,5,7,11 and others are composite numbers. How to differentiate these numbers, these numbers have only two factors like factors. If we put the prime number up to 100 in a row then these numbers are as follows, 2,3,5,7,11,13,17,19,23,29,31,
And the natural number is of two types they are Prime numbers and Composite numbers.
When a given number can be divide by the number 1 and by the number itself those numbers are called Prime numbers. So, in other words, we can say that all the natural number which can be divided by the number itself or by the number 1. Let us understand it with some examples it will help us in understanding much better what Prime numbers are. All the prime numbers are always greater and bigger than 1.
Some Major points of Prime Numbers.
- The prime numbers are always bigger than 1.
- The prime number can be divided by the number 1.
- The prime numbers can be divided by the number itself.
- The prime numbers have just two factors.
For an example of Prime Numbers,
If we take the number 2 so this number can have the factor 2 and 1, this number can be divided by 1 and 2 only and the number 2 is greater than 1.
If we take the number 3 so this number can have the factor 3 and 1, this number can be divided by 1 and 3 only and the number 3 is greater than 1.
If we take the number 5 so this number can have the factor 5 and 1, this number can be divided by 1 and 5 only and the number 5 is greater than 1.
If we take the number 7 so this number can have the factor 7 and 1, this number can be divided by 1 and 7 only and the number 7 is greater than 1.
If we take the number 11 so this number can have the factor 11 and 1, this number can be divided by 1 and 11 only and the number 11 is greater than 1.
If we take the number 17 so this number can have the factor 17 and 1, this number can be divided by 1 and 17 only and the number 17 is greater than 1.
If we take the number 19 so this number can have the factor 19 and 1, this number can be divided by 1 and 19 only and the number 19 is greater than 1.
and the list is so big you can move ahead with other numbers and find the prime numbers.
And here we can notice one thing in the prime numbers that is it has only two factors.
Hope it will help you in understanding what Prime numbers are and the example which we have given here will going to help you a lot for knowing what prime numbers are all about. ENJOY!
