Prime Numbers 1 to 10
A prime number is a positive natural number that has two factors, which are 1 and the same number. Prime numbers are always greater than 1. Out of the first 10 natural numbers, there are four prime numbers. They are 2,3,5 and 7. These numbers are said to be prime as they do not have any other factors other than 1, and the number itself. 2 and 3 are two consecutive prime numbers. Let us learn more about how to find the prime numbers from 1 to 10 and the list of these prime numbers in this article.

How to Find Prime Numbers From 1 to 10?
Prime numbers are completely divisible by 1 and themselves, which means there are no remainders upon division by 1 and the same number. Considering the numbers from 1 to 10 we have four prime numbers. Let us look at how can we find if a number from 1 to 10 is prime or not. Follow the steps mentioned below to find the prime numbers from 1 to 10. Let us represent the number between 1 to 10 as 'n'. This is called the factorization method of finding prime numbers.
Step 1: Find the list of factors of each number from 1 to 10.
Step 2: If the factors are only 1 and the number itself, then it is a prime number.
Step 3: If the factors are more than 2 (excluding 1 and the number), then it is not a prime number.
Let us apply the steps for all the numbers from 1 to 10 and check if they are prime in the below table:
Number  Factors  Prime or Not Prime 
1  1  Neither a prime nor a composite number. 
2  1 and 2  There are only two factors (1 and the number 2). Therefore, 2 is a prime number. 
3  1 and 3  There are only two factors (1 and the number 3). Therefore, 3 is a prime number. 
4  1,2 and 4  There are more than two factors other than 1 and the number 4. Therefore, 4 is not a prime number. 
5  1 and 5  There are only two factors (1 and the number 5). Therefore, 5 is a prime number. 
6  1,2, 3 and 6  There are more than two factors other than 1 and the number 6. Therefore, 6 is not a prime number. 
7  1 and 7  There are only two factors (1 and the number 7). Therefore, 7 is a prime number. 
8  1,2,4 and 8  There are more than two factors other than 1 and the number 8. Therefore, 8 is not a prime number. 
9  1,3 and 9  Factors are 1,3 and 9. There are more than two factors other than 1 and the number 9. Therefore 9 is not a prime number. 
10  1,2,5 and 10  There are more than two factors other than 1 and the number 10. Therefore, 10 is not a prime number.

Important Notes on Prime Numbers From 1 to 10
Here is a list of a few points that should be remembered while studying prime numbers from 1 to 10.
 1 is neither considered to be a prime nor a composite number.
 All prime numbers are natural numbers.
 2 is the only even prime number between 1 and 10.
 2 and 3 are two consecutive prime numbers between 1 and 10.
 Except 2, the prime numbers 3, 5, and 7 can be expressed as a sum of any two prime numbers. For example, 7 can be expressed as a sum of 2 and 5.

Solved Examples

Example 1: Are all odd numbers between 1 to 10 prime numbers? Give reasons to justify your answer.
Solution:
The odd numbers between 1 and 10 are 1,3,5,7,9. If a number has more than two factors other than (1 and the number) it is not a prime number. 1 is neither a prime nor a composite number. The numbers 3,5 and 7 have only two factors which are 1 and the same number (which is 3, 5, and 7). So they are prime numbers. Number 9 has three factors which are 1,3, and 9. Since there are three factors for 9, it is not a prime number.
Therefore, not all the odd numbers between 1 to 10 are prime, except 3,5, and 7. 
Example 2: What are the common factors for all the prime numbers from 1 to 10? Also, find out if 10 is a prime number?
Solution:
The common factor for all prime numbers from 1 to 10 is 1 since 1 is divisible by every number. The other factors for prime numbers from 1 to 10 are the same number. 10 is not a prime number since it has four factors, which are 1,2,5, and 10.
FAQs on Prime Numbers From 1 to 10
What Are the Prime Numbers From 1 to 10?
There are 4 prime numbers from 1 to 10. They are 2,3,5 and 7.
Is There an Even Prime Number From 1 to 10?
Yes, 2 is an even prime number from 1 to 10. Since 2 has only two factors (1 and itself, which is 2), it is a prime number and is the only even prime number from 1 to 10.
What are the Odd Prime Numbers From 1 to 10?
The odd numbers from 1 to 10 are 1,3,5,7 and 9. 1 is not considered as a prime or a composite number. The number 9 also has 3 factors which are (1,3 and 9), so it is not a prime number. 3,5 and 7 are odd prime numbers from 1 to 10, as each of these numbers has only 2 factors, which are 1 and the same number.
How to Find Prime Numbers From 1 to 10?
Prime numbers from 1 to 10 are 2,3,5 and 7. To find if a number between 1 and 10 is prime or not, please follow the steps mentioned below.
Step 1: Find the factors of every number from 2 to 10. 1 is to be ignored as it is neither a prime nor a composite number.
Step 2: If there are any other factors other than (1 and the same number) then it is not a prime number. For example, 4 has 1,2, and 4 as factors, so it is not a prime number.
Step 3: If step 2 holds good for a number, then we classify it as a prime number.
What is the Smallest and Largest Prime Number From 1 to 10?
There are a total of 4 prime numbers from 1 to 10. They are 2,3,5 and 7. 2 is the smallest and 7 is the largest prime number from 1 to 10.
