Introduction to define prime
Normally the word prime is defined as “first, importance, greatest position, highest order, basics, and fundamentals”. In mathematics prime defines the prime number. Prime number is a whole number that is evenly divisible by 1 and the number itself. A natural number that has exactly two distinct divisors such as 1 and itself is called prime number (or simply a prime).There is infinity of prime numbers exist. The density of prime number compared to natural numbers is 0. The numbers 0 and 1 are not a prime number. Other than prime numbers are called composite numbers.

How to calculate the prime numbers?
1 `->` The number is not a prime or composite.
2 `->` 1x2 = 2 and 2x1 =2. The number is divisible by 1 and itself (2), therefore this is even prime number.
3 `->` 1x3 = 3 and 3x1 = 3. The number is divisible by 1 and itself (3), therefore this is a prime number
4 `->` 1x4 = 4, 2x2 = 4 and 4x1 =4. The number is divisible by 1, 2 and itself (4), therefore this is a composite number.
5 `->` 1x5 = 5 and 5x1 =5. The number is divisible by 1 and itself (5), therefore this is a prime number.
6 `->` 1x6 =6, 2 x3=6, 3x2 =6 and 6 x 1 = 6. The number is divisible by 1, 2, 3 and itself (6). Therefore this is a composite number.
7 `->` 1x7 = 7 and 7x1= 7. The number is divisible by 1 and itself (7), therefore this is a prime number. I like to share this money math with you all through my article.
Example – Define Prime
Problem 1: Give the prime number from 10 to 20
Solution: Let us consider the values from 10 to 20 as
10 have divisors 1, 2, 5 and 10. This is composite number.
11 have divisors 1 and 11. This is prime number.
12 have divisors 1, 2,3,4,6 and 12. This is composite number.
13 have divisors 1 and 13. This is prime number.
14 have divisors 1, 2, 7 and 14. This is composite number.
15 have divisors 1, 3, 5 and 15. This is composite number.
16 have divisors 1,2,4,8 and 16. This is composite number.
17 have divisors 1 and 17. This is prime number.
18 have divisors 1, 2, 9 and 18. This is composite number.
19 have divisors 1 and 19. This is prime number.
20 have divisors 1, 2, 4,5,10 and 20. This is composite number
