Introduction to Math prime numbers:
In mathematics, a prime number (or a prime) is a natural number that has exactly two distinct natural number divisors: 1 and itself. The first twenty-five prime numbers are:
Prime Numbers:- 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.
Condition: - If x is the prime number then the next factors of the number x is 1 and X. - Source from Wikipedia
Prime numbers in math:
To finding a prime number up to 100 means we can calculate directly but we need to find above hundred means we have follow the shortcut method.
For example:
Check if 131 is a prime number.
Step 1:
Now we have to take Square root for 131 = 11.44
Now rounding the value 11.4 to the nearest big whole number. We can write 11.4 as 12.
Step 2:
Then find the Prime Numbers below 12. The factors up to 12 are 2, 3, 5, 7, 1
Step 3:
The given number 131 is not divisible by 2, 3, 5, 7 and 11
131 is divisible by and the number itself.
So the number 131 is considered as prime number.
Example problems for math prime number:
Problem 1:
Find whether the number 53 is prime number or not?
Solution:
The given number 53 is a prime number. Why means it includes two factors 1 and 53 only. So the number 53 is a prime number.
Problem 2:
Find whether the number 79 is prime number or not?
Solution;
The given number 79 is divisible by one and itself only. So it is called as prime number.
Problem 3:
Find whether the number 39 is prime number or not?
Solution:
The given number 39 has more than two factors. That is 1, 6, 13 and 39. Hence the given number 39 is not a prime number.
Problem 4:
Find whether the number 434 is prime number or not?
Solution;
The given number 434 has more than two factors. That is 1, 2, 7, 31, 217, and 434. Hence the given number 434 is not a prime number.
Problem: - 5
Find whether the number 638 is prime or not?
Solution:
The given number is 638 has divided by two. So the factors for 638 are 1,2, 11, 29, 319 and 638. Hence 638 is not a prime number.
