The natural numbers greater than 1 are called prime numbers. Prime numbers have only two factors, 1 and the number itself. Besides math, we use prime numbers in many fields, such as securing digital data, radio frequency identification, etc. In this topic, we will learn about the prime numbers 1 to 10000.
A prime number is a natural number with no positive factors other than 1 and the number itself.
The prime number can only be evenly divisible by 1 and itself. Here are some basic properties of prime numbers:
Every number greater than 1 is divisible by at least one prime number.
Two prime numbers are always relatively prime to each other.
Every even positive integer greater than 2 can be written as the sum of two prime numbers.
Every composite number can be uniquely factored into prime factors.
Except for 2, all prime numbers are odd; 2 is the only even number.
A prime number chart is a table showing the prime numbers in increasing order.
The chart includes all the prime numbers up to a certain limit for identifying the prime numbers within a range.
For kids, it will be less difficult to understand the prime numbers through the chart.
The significance of this prime number chart is used in different fields like the foundation of mathematics and the fundamental theorem of arithmetic.
The list of all prime numbers from 1 to 10000 provides a comprehensive view of numbers in this range that can only be divided by 1 and the number itself. The prime numbers in the range of 1 to 10000 include
Prime numbers and odd numbers are the numbers that are only divisible by 1 and the number itself.
They cannot be evenly divisible by 2 or other numbers. 2 is the only even prime number, which divides all the non-prime numbers.
Therefore, except for 2, all prime numbers are considered as the set of odd numbers.
Prime numbers are a set of natural numbers that can only be divided by 1 and the number itself.
Here are two important ways to find whether a number is prime or not.
By Divisibility Method: To find whether a number is prime or not, we use the divisibility method to check. If a number is divisible by 2, 3, or 5 then it will result in a non-prime number.
Prime numbers are only divisible by 1 and themselves, so if a number is divisible by the number itself and 1, it is a prime number.
For example: To check whether 97 is a prime number,
Step 1: 97 ÷ 2 = 48.5 (remainder ≠ 0)
Step 2: 97 ÷ 3 = 32.33 (remainder ≠ 0)
Step 3: 97 ÷ 5 = 19.4 (remainder ≠ 0) Since no divisors are found, 97 is a prime number.
By Prime Factorization Method: The prime factorization method is the process of breaking down the composite number into the product of its prime factors.
The method of prime factorization helps to identify the prime numbers up to 10000 by building the smallest blocks of any given number.
For example: The prime factorization of 10000: Let's break it down into the smallest prime numbers until it can’t divide anymore.
Step 1: 10000 ÷ 2 = 5000
Step 2: Now, we divide 5000, 5000 ÷ 2 = 2500
Step 3: Divide 2500, 2500 ÷ 2 = 1250
Step 4: Divide 1250, 1250 ÷ 2 = 625
Step 5: Divide 625, since 625 ends in 5, divide the number with 5 625 ÷ 5 = 125
Step 6: Divide 125, 125 ÷ 5 = 25
Step 7: Divide 25, 25 ÷ 5 = 5
Step 8: At last, take 5. 5 ÷ 5 = 1 (since 5 is a prime number, and dividing by 5 gives 1)
Therefore, the prime factorization of 10000 is: 10000 = 2⁴ × 5⁴.
Rule 1: Divisibility Check: Prime numbers are natural numbers that are greater than 1 and have no divisors other than 1 and the number itself. In the divisibility check rule, we check whether the prime number is divisible by 2, 3, 5, and 7. If it's divisible by these numbers then it's not a prime number.
Rule 2: Prime Factorization: In this prime factorization method, we break down all the numbers into their prime factors, showing them as the product of prime numbers.
Rule 3: Sieve of Eratosthenes Method: The method, sieve of Eratosthenes is an ancient algorithm used to find all prime numbers up to a given limit.
First, we list all the numbers from 1 to 10000. Then start with the first prime number,
2. Mark all the multiples of 2 as non-prime. Repeat the process for the next unmarked prime number and continue until you reach the square root of 10000, approximately 100. The remaining unmarked numbers are the prime numbers.
Tips and Tricks for Prime Numbers 1 to 10000
Use common shortcuts to memorize the prime numbers. 2, 3, 5, 7, 11, 13, 17, 19, 23, 29 use these numbers as reference.
Practice using the method of Sieve of Eratosthenes efficiently. Numbers like 4, 8, 9, 16, 25, 36 are never meant to be prime.
Knowing the common powers of numbers helps in avoiding unnecessary checks.
While working with the prime numbers 1 to 10000, children might encounter some errors or difficulties. We have many solutions to resolve those problems. Here are some given below:
Is 7919 a prime number?
Yes, 7919 is a prime number.
The square root of 7919 is √7919 ≈ 88.95.
We check divisibility by primes less than 88.95 (2, 3, 5, 7, 11, 13, 17, 19, ... up to 83).
7919 ÷ 2 = 3959.5 7919 ÷ 3 = 2639.67 7919 ÷ 5 = 1583.8 7919 ÷ 7 = 1131.28 7919 ÷ 11 = 719.909 ...
Since 7919 is not divisible by any of these numbers, 7919 is a prime number.
An engineer wants to choose a large prime number as a key for encryption. They decide to use the largest prime number under 10000. Which prime number should they choose?
The largest prime number under 10000 is 9973.
Prime numbers are natural numbers that are greater than 1 and have no divisors other than 1 and the number itself.
The prime numbers under 10000 are numerous, and 9973 is the largest prime number under 10000.
Therefore, the engineer should use 9973 as the encryption key.
A mathematician is studying prime numbers and wants to find the prime numbers that are closest to 150 but less than 150.
149 is the prime number which is closest to 150.
149 is a prime number because it is only divisible by 1 and the number itself.
The next prime number after 149 is 151, which is greater than 150.
Therefore, the prime number closest to 150 and less than 150 is 149.
