3 <p>Prime numbers define those numbers that have 2 factors (1 and number itself). These numbers can be used in computer security or cryptography, designing computer algorithms, etc. We will know more about Prime numbers and check whether 6 is a prime number or not.</p>

4 <h2>Is 6 a Prime Number?</h2>

5 <p>Numbers can be either prime or composite. 6 is not a<a>prime number</a>, since<a>factors</a>of 6 are 1,2,3 and 6. That means it is not a prime number. So, we can say that 6 is a<a>composite number</a>.</p>

6 <p> </p>

7 <h2>Why is 6 a Prime Number?</h2>

8 <p>We will now check through various methods that if 6 is a prime<a>number</a>or not. Let’s proceed.</p>

13 </ul><h2>Using the Counting Divisors Method</h2>

14 <p>The only condition this method involves is that a particular number is prime if and only if it has two distinct<a>integers</a>as its divisors. In case of 6, the distinct divisors are: 1,2,3, and 6. Hence, there exist more than two divisors of 6.</p>

15 <p>Hence, 6 is not prime. </p>

17 <h3>Using the Divisibility Test Method</h3>

19 <p>In the divisibility method, we have to check 6 with different numbers whether 6 is divisible or not. The rule is, if 6 is divisible by any number that falls between 2 and the<a>square</a>root of 6 itself, it is composite. </p>

20 <p><strong>Step 1:</strong>Checking divisibility by 2</p>

22 <p>Any<a>even number</a>is divisible by 2. Also, the square root of 6 is<a>less than</a>3, so no need to check divisibility<a>greater than</a>2.</p>

23 <p> 6/2 =3. So, 6 is perfectly divisible by 2.</p>

22 <p> 6/2 =3. So, 6 is perfectly divisible by 2.</p>

24 <p>We can conclude that 6 is not a prime number and 6 is divisible by numbers other than 1 and 6. </p>
