3 <p>For this question, where the answer is yes. Since the number two is an even number, many believe that 2 is not a prime number. But, 2 is a very special number! We will learn more about Prime numbers and check whether 2 is a prime number or not. (Computer use the base-2 system(binary) to represent data - zero and one are the only digits.</p>

4 <h2>Is 2 a Prime Number?</h2>

5 <p>Yes, 2 is a<a>prime number</a>. Where a prime number is a number that can only be divided by itself and one without holding remainders. The<a>factors</a>of 2 are 1 and 2. </p>

6 <p>Since there are only two factors of 2, it shows that 2 is a prime number.</p>

7 <p> </p>

8 <h2>Why is 2 a prime number?</h2>

9 <p>Because the<a>number</a>2 holds only two different divisors, as it meets the condition of having any other factors except 1 and itself.</p>

10 <p>Listed below are the methods by which we can devise if a particular number is prime or not;</p>

15 </ul><h3>Using the Counting Divisors Method</h3>

16 <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.</p>

17 <p>In the case of 2, the only two distinct divisors are: 1 and 2</p>

18 <p>Hence, 2 is prime. </p>

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

22 <p>The<a>divisibility rule</a>of 2 helps us find whether a number is a<a>multiple</a>of 2 or not without performing the actual<a>division</a>. The divisibility rule of 2 states that if the last digit of a number is divisible by 2 that is, the last digit is 0, 2, 4, 6, or 8, then the number is also divisible by 2. </p>
