Prime Numbers List: Definition, Examples, and Complete Table (1 to 1000)

Simply put, a prime number is any positive integer greater than 1 that can only be divided by 1 and itself without a remainder (e.g., 2, 3, 5, 7, 11). There are 25 prime numbers between 1 and 100, and 168 prime numbers from 1 to 1,000.

Key Prime Number Rules at a Glance:

1. 2 is unique: It is both the smallest prime number and the only even prime number.
2. 1 is NOT prime: A prime number must have exactly two factors. 1 only has one factor.
3. Formulas to test primes: Most primes can be expressed in the form of $6n \pm 1$.

What are Prime Numbers?

Prime numbers are numbers that have only two factors, that are, 1 and the number itself. For example, 3 is only divisible by 1 and 3. Therefore, 3 is a prime number! 7 is also a prime number because its only factors are 1 and 7.

Let’s look at the number 6. 6 is divisible by 1, 2, 3, and 6, so it has four factors, 1, 2, 3, and 6. It has more than two factors. Therefore, it is not prime, it is a composite number.

You can quickly find out the factors of a number by multiplying it.

Prime Numbers Definition

A prime number is any positive integer that is divisible only by itself and the number 1. This is the most basic definition of a prime number.

The first ten prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29.

Note: It is important to note that 1 is neither prime nor composite because it has only one factor, which is itself. It is a unique number.

Properties of Prime Numbers

If you are unsure whether a number is a prime number, you can determine this by following the properties of prime numbers listed below.

• Prime numbers are natural numbers greater than 1. Every number greater than 1 can be divided by at least one prime number.
• 2 is the smallest prime number.
• 2 is the only even prime number. All the prime numbers except 2 are odd numbers.
• Any two distinct prime numbers are always coprime to each other.
• Every even positive integer greater than 2 can be expressed as the sum of two primes.
• Every positive integer greater than 1 has at least one prime factor.
• Each composite number can be factored into prime factors and individually all of these are unique.

Odd Prime Numbers List

It is worth noting that all primes are odd except for the number 2, which is even. Interestingly, 2 is the only even prime number. This means that the list of odd primes can start at 3 and go on from there since the rest of the primes are odd.

For example, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, and so on are all odd primes.

Twin Prime Number List

As a reference, in this section, we will give you some information about twin prime numbers.

Two prime numbers are called twin prime numbers if there is only one composite number between them. In other words, two prime numbers with a difference of 2 are called twin prime numbers.

• For example, (3,5) is a twin prime because the difference between the two numbers is 5 - 3 = 2.

The alternative names, given to twin primes are prime twin or prime pair.

Prime And Composite Numbers

• A prime number is a number greater than 1 that has exactly two factors, whereas a composite number has more than two factors. For example, 5 has only one factor, 1 × 5 (or) 5 × 1. Therefore, 5 is a prime number.
• A composite number is a number greater than 1 that has more than two factors. For example, 4 has more than one factor and the factors of 4 are 1, 2, and 4. It has more than two factors and hence, 4 is a composite number.

Let us understand the difference between prime numbers and composite numbers with the help of the table below:

Prime Numbers	Composite Numbers
Numbers, greater than 1, having only two factors, 1 and the number itself	Numbers greater than 1 having at least three factors
2 is the smallest and the only even prime number	4 is the smallest composite number
Examples of prime numbers are 2, 3, 5, 7, 11, 13, and so on.	Examples of composite numbers are 4, 6, 8, 9, 10, and so on.

How to Find Prime Numbers?

Above we covered the basic information about prime numbers, so how can you tell if a number is prime or not? How do you find out the prime numbers? The following two methods will help you to find whether the given number is a prime or not.

Method 1

We know that 2 is the only even prime number. And only two consecutive natural numbers, 2 and 3, are prime. Apart from those, every prime number can be written as 6n + 1 or 6n - 1 (except for multiples of primes, i.e., 2, 3, 5, 7, 11), where n is a natural number.

For example:

6(1) – 1 = 5

6(1) + 1 = 7

6(2) – 1 = 11

6(2) + 1 = 13

6(3) – 1 = 17

6(3) + 1 = 19

6(4) – 1 = 23

6(4) + 1 = 25 (multiple of 5)

Method 2

To find out the number of primes greater than 40, you can use the following formula.

n² + n + 41, where n = 0, 1, 2, ….., 39

For example:

(0)² + 0 + 41 = 41

(1)² + 1 + 41 = 43

(2)² + 2 + 41 = 47

You can type any number from 1 to 1000 to see if it’s a "Prime Hero" or a "Composite Monster" instantly!

Let's look at some classic examples to see how it works in detail:

Example 1. From the list of prime numbers 1 to 1000 given above, find if 825 is a prime number or not.

Answer: The list of prime numbers from 1 to 1000 does not include 825 as a prime number.

• It is a composite number since it has more than two factors. We can confirm this by prime factorization of 825 also.
• Prime Factorization of 825 = 3¹ x 5² x 11¹
• Hence, 825 includes more than two factors.

Example 2. Is 10 a Prime Number?

Answer: No, because it can be divided evenly by 2 or 5, 2×5=10, as well as by 1 and 10.

• Alternatively, using method 1, let us write in the form of 6n ± 1.
• 10 = 6(1) + 4 = 6(2) – 2
• This is not of the form 6n + 1 or 6n – 1.
• Hence, 10 is not a prime number.

Example 3. What is the greatest prime number between 80 and 90?

Answer: The prime numbers between 80 and 90 are 83 and 89.

So, 89 is the greatest prime number between 80 and 90.

Example 4. What are prime numbers between 1 and 50?

The list of prime numbers between 1 and 50 are:

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47.
