<p>The numbers that have only two factors which are 1 and itself are called prime numbers. For encryption, computer algorithms, barcode generation, prime numbers are used. In this topic, we will be discussing whether 900 is a prime number or not.</p>

<p>There are two<a>types of numbers</a>, mostly - Prime numbers and<a>composite numbers</a>, depending on the number of<a>factors</a>. A<a>prime number</a>is a<a>natural number</a>that is divisible only by 1 and itself. For example, 3 is a prime number because it is divisible by 1 and itself.</p>

<p>A composite number is a positive number that is divisible by more than two numbers. For example, 6 is divisible by 1, 2, 3, and 6, making it a composite number.</p>

</ul><h2>Why is 900 Not a Prime Number?</h2>
14
-
<p>The characteristic<a>of</a>a prime number is that it has only two divisors: 1 and itself. Since 900 has more than two factors, it is not a prime number. A few methods are used to distinguish between prime and composite numbers. These methods include: -</p>

</ol><h2>Using the Counting Divisors Method</h2>
20
-
<p>The method in which we count the number of divisors to categorize the numbers as prime or composite is called the counting divisors method. Based on the count of the divisors, we categorize prime and composite numbers. -</p>
21
-
<ul><li>If there is a total count of only 2 divisors, then the number would be prime. </li>
22
-
<li>If the count is more than 2, then the number is composite.</li>
23
-
</ul><p>Let’s check whether 900 is prime or composite.</p>
24
-
<p><strong>Step 1:</strong>All numbers are divisible by 1 and itself.</p>
25
-
<p>Step 2: Divide 900 by 2. It is divisible by 2, so 2 is a factor of 900.</p>
26
-
<p><strong>Step 3:</strong>Divide 900 by 3. It is divisible by 3, so 3 is a factor of 900.</p>
27
-
<p><strong>Step 4:</strong>You can simplify checking divisors up to 900 by finding the root value. We then need to only check divisors up to the root value.</p>
28
-
<p><strong>Step 5:</strong>When we divide 900 by 2, 3, 5, and other numbers, it is divisible by many including 2, 3, 5, and 10.</p>
29
-
<p>Since 900 has more than 2 divisors, it is a composite number.</p>

<h2>Using the Divisibility Test Method</h2>
33
-
<p>We use a<a>set</a>of rules to check whether a number is divisible by another number completely or not. This is called the Divisibility Test Method. </p>
34
-
<p><strong>Divisibility by 2:</strong>The number in the ones'<a>place value</a>is 0, which means that 900 is divisible by 2. </p>
35
-
<p><strong>Divisibility by 3:</strong>The<a>sum</a>of the digits in the number 900 is 9. Since 9 is divisible by 3, 900 is divisible by 3. </p>
36
-
<p><strong>Divisibility by 5:</strong>The unit’s place digit is 0. Therefore, 900 is divisible by 5. </p>
37
-
<p><strong>Divisibility by 7:</strong>Check divisibility by performing the specific test for 7. Since it doesn't divide exactly, 900 is not divisible by 7. </p>
38
-
<p><strong>Divisibility by 11:</strong>In 900, the sum of the digits in odd positions is 9, and the sum of the digits in even positions is 0. The difference is 9, which means 900 is not divisible by 11.</p>
39
-
<p>Since 900 is divisible by more than two numbers, it is a composite number.</p>

<h2>Using Prime Number Chart</h2>
41
-
<p>The prime number chart is a tool created by using a method called “The Sieve of Eratosthenes.” In this method, we follow these steps:</p>
42
-
<p><strong>Step 1:</strong>Write numbers from 1 to 1000 in rows and columns.</p>
43
-
<p><strong>Step 2:</strong>Leave 1 without coloring or crossing, as it is neither prime nor composite.</p>
44
-
<p><strong>Step 3:</strong>Mark 2 because it is a prime number and cross out all the<a>multiples</a>of 2.</p>
45
-
<p><strong>Step 4:</strong>Mark 3 because it is a prime number and cross out all the multiples of 3.</p>
46
-
<p><strong>Step 5:</strong>Repeat this process until you reach the table consisting of marked and crossed boxes, except 1. Through this process, we will have a list of prime numbers.</p>
47
-
<p>Since 900 is not present in the list of prime numbers, it is a composite number.</p>
48
-
<h2>Using the Prime Factorization Method</h2>
49
-
<p>Prime factorization is a process of breaking down a number into<a>prime factors</a>and then multiplying those factors to obtain the original number.</p>
50
-
<p><strong>Step 1:</strong>We can write 900 as 9 × 100.</p>
51
-
<p><strong>Step 2:</strong>Break down 9 into 3 × 3 and 100 into 10 × 10.</p>
52
-
<p><strong>Step 3:</strong>Further break down 10 into 2 × 5. Step 4: Now we get the<a>product</a>consisting of only prime numbers.</p>
53
-
<p>Hence, the prime factorization of 900 is 2 × 2 × 3 × 3 × 5 × 5.</p>
