3 <p>The numbers that have only two factors, which are 1 and themselves, are called prime numbers. Prime numbers are used in encryption, computer algorithms, and barcode generation. In this topic, we will be discussing whether 697 is a prime number or not.</p>

4 <h2>Is 697 a Prime Number?</h2>

5 <p>There are two<a>types of numbers</a>, mostly -</p>

6 <p>Prime numbers and<a>composite numbers</a>, depending on the number of<a>factors</a>.</p>

7 <p>A<a>prime number</a>is a<a>natural number</a>that is divisible only by 1 and itself.</p>

8 <p>For example, 3 is a prime number because it is divisible by 1 and itself.</p>

9 <p>A composite number is a positive number that is divisible by more than two numbers.</p>

10 <p>For example, 6 is divisible by 1, 2, 3, and 6, making it a composite number.</p>

11 <p>Prime numbers follow a few properties, such as:</p>

12 <ul><li>Prime numbers are positive numbers always<a>greater than</a>1.</li>

13 </ul><ul><li>2 is the only even prime number.</li>

14 </ul><ul><li>They have only two factors: 1 and the number itself.</li>

15 </ul><ul><li>Any two distinct prime numbers are<a>co-prime numbers</a>because they have only one common factor that is 1.</li>

16 </ul><p>As 697 has more than two factors, it is not a prime number.</p>

17 <h2>Why is 697 Not a Prime Number?</h2>

18 <p>The characteristic<a>of</a>a prime number is that it has only two divisors: 1 and itself.</p>

19 <p>Since 697 has more than two factors, it is not a prime number.</p>

20 <p>A few methods are used to distinguish between prime and composite numbers.</p>

21 <p>Some methods include:</p>

22 <ul><li>Counting Divisors Method </li>

23 <li>Divisibility Test </li>

24 <li>Prime Number Chart </li>

25 <li>Prime Factorization</li>

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

27 <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>

28 <ul><li>If there is a total count of only 2 divisors, then the number would be prime. </li>

29 <li>If the count is more than 2, then the number is composite.</li>

30 </ul><p>Let’s check whether 697 is prime or composite.</p>

31 <p><strong>Step 1:</strong>All numbers are divisible by 1 and themselves.</p>

32 <p><strong>Step 2:</strong>Divide 697 by 2. It is not divisible by 2, so 2 is not a factor of 697.</p>

33 <p><strong>Step 3:</strong>Divide 697 by 3. It is not divisible by 3, so 3 is not a factor of 697.</p>

34 <p><strong>Step 4:</strong>Continue checking divisors up to the<a>square</a>root of 697, which is approximately 26.41.</p>

35 <p><strong>Step 5:</strong>When we divide 697 by 17, it is divisible by 17 and gives a<a>quotient</a>of 41, which shows that 17 and 41 are factors of 697.</p>

36 <p>Since 697 has more than 2 divisors, it is a composite number.</p>

41 <p><strong>Divisibility by 2:</strong>697 is not even, so it is not divisible by 2.</p>

40 <p><strong>Divisibility by 2:</strong>697 is not even, so it is not divisible by 2.</p>

42 <p><strong>Divisibility by 3:</strong>The<a>sum</a>of the digits in the number 697 is 22. Since 22 is not divisible by 3, 697 is also not divisible by 3.</p>

41 <p><strong>Divisibility by 3:</strong>The<a>sum</a>of the digits in the number 697 is 22. Since 22 is not divisible by 3, 697 is also not divisible by 3.</p>

43 <p><strong>Divisibility by 5:</strong>The unit’s place digit is 7, so 697 is not divisible by 5.</p>

42 <p><strong>Divisibility by 5:</strong>The unit’s place digit is 7, so 697 is not divisible by 5.</p>

44 <p><strong>Divisibility by 7:</strong>Doubling the last digit (7 × 2 = 14) and subtracting from the rest (69 - 14 = 55) gives 55, which is divisible by 7. So, 697 is divisible by 7.</p>

43 <p><strong>Divisibility by 7:</strong>Doubling the last digit (7 × 2 = 14) and subtracting from the rest (69 - 14 = 55) gives 55, which is divisible by 7. So, 697 is divisible by 7.</p>

45 <p><strong>Divisibility by 11</strong>: The alternating sum is (6 - 9 + 7 = 4), which is not divisible by 11. Since 697 is divisible by 7, it has more than two factors and is a composite number.</p>

44 <p><strong>Divisibility by 11</strong>: The alternating sum is (6 - 9 + 7 = 4), which is not divisible by 11. Since 697 is divisible by 7, it has more than two factors and is a composite number.</p>
