3 <p>Mathematicians have a saying that prime numbers are the cool kids. They have two factors: 1 and the number. Prime numbers are used in music and also in coding languages. So let us jump into prime numbers and determine why 56 is not a prime number.</p>

4 <h2>Is 56 a Prime Number?</h2>

5 <p>Did you know 56 isn’t a<a>prime number</a>? But why? Let us look at the rules a number has to follow to be a prime number to be a prime number.</p>

6 <ul><li>It should have only 2<a>factors</a>: 1 and itself.</li>

7 </ul><ul><li>It should have just 2 divisors.</li>

8 </ul><p>In the rules which satisfy the 2 above, every number that comes next is of a prime number. </p>

9 <h2>Why is 56 not a prime number?</h2>

10 <p>We could find that a<a>number</a>is prime if it has 2 factors only, 1 and the number itself. It means that a number, not satisfying these conditions, cannot be a prime number. However, there are pretty simple methods to determine whether a number is prime or not:</p>

11 <ul><li>Count Divisor Method</li>

12 </ul><ul><li>Divisibility Test</li>

13 </ul><ul><li>Prime Number Table</li>

14 </ul><ul><li>Prime Factorization</li>

15 </ul><p>Let's see how each of these tests helps us in finding prime numbers. </p>

16 <h3>Using the Counting Divisors Method</h3>

17 <p>The name implies: We’re counting how many divisors a given number has, and then saying that number is prime. It is easy to learn. With that said, let’s see what steps are there in this method.</p>

18 <ul><li>Divisors of 56: 1,2,4,7,8,14,28 and 56.</li>

19 </ul><ul><li>Number of divisors: 8</li>

20 </ul><p>We can see that number 56 has eight divisors. And we see that it doesn’t fulfill the criteria needed for a prime number. So it is not a prime number.</p>

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

24 <p>Let's check 56 is divisible by how many numbers. If 56 is divisible by even one of the numbers, then it will not be a prime number. Let's check the divisibility with 2,3,5 and 7. </p>

23 <p>Let's check 56 is divisible by how many numbers. If 56 is divisible by even one of the numbers, then it will not be a prime number. Let's check the divisibility with 2,3,5 and 7. </p>

25 <ul><li>That is, any number ending in an<a>even number</a>is divisible by 2. And 56 ends with an even number. Actually, 6 is a<a>multiple</a>of 2, so it is an even number. So that 56 will be divisible by 2 and it is not a prime number.</li>

26 </ul><ul><li>The<a>sum</a>of the digits of the number 56 is 11. Now, in order to be divisible by 3, the sum of the digits needs to be a multiple of 3. Since 11 is not a multiple of 3. Therefore, 56 is not divisible by 3.</li>

27 </ul><ul><li>It does not end in 0 or 5. To be divisible by 5 a number should end in 0 or 5. So, 56 cannot be divided by 5.</li>

26 </ul><ul><li>It does not end in 0 or 5. To be divisible by 5 a number should end in 0 or 5. So, 56 cannot be divided by 5.</li>

28 </ul><ul><li>We know how to see whether 56 is divisible by 7. Let's simply glance at the last digit, which is 6. We have doubled that 6 to get 12, then subtract the other digit, which is 5. So, we do 12 - 5 = 7. Since 7 is a multiple of 7, it means that 56 is divisible by 7.</li>
