3 <p>The natural numbers greater than 1 are called prime numbers. Prime numbers have only two factors, 1 and the number itself. Besides math, we use prime numbers in many fields, such as securing digital data, radio frequency identification, etc. In this topic, we will learn about the prime numbers 1 to 101.</p>

4 <h2>Prime Numbers 1 to 101</h2>

5 <p>A<a>prime number</a>is a<a>natural number</a>with no positive<a>factors</a>other than 1 and the number itself. A prime number can only be evenly divisible by 1 and the number itself. Here are some basic properties of prime numbers: -</p>

6 <ul><li>Every number<a>greater than</a>1 is divisible by at least one prime number. </li>

7 <li>Two distinct prime numbers are always<a>relatively prime</a>to each other. </li>

8 <li>Every even<a>positive integer</a>greater than 2 can be written as the<a>sum</a>of two prime numbers. </li>

9 <li>Every composite number can be uniquely factored into prime factors. </li>

10 <li>Except for 2, all prime numbers are odd; 2 is the only even prime number.</li>

22 <h2><strong>By Divisibility Method:</strong></h2>

24 <p>To find whether a number is prime or not, we use the divisibility method to check. If a number is divisible by 2, 3, or 5 then it will result in a non-prime number. Prime numbers are only divisible by 1 and themselves, so if a number is divisible by the number itself and 1, it is a prime number. For example: To check whether 29 is a prime number,</p>

Prime numbers are only divisible by 1 and themselves, so if a number is divisible by the number itself and 1, it is a prime number. For example: To check whether 29 is a prime number,</p>

25 <p><strong>Step 1:</strong>29 ÷ 2 = 14.5 (<a>remainder</a>≠ 0)</p>

24 <p><strong>Step 1:</strong>29 ÷ 2 = 14.5 (<a>remainder</a>≠ 0)</p>

26 <p><strong>Step 2:</strong>29 ÷ 3 = 9.66 (remainder ≠ 0)</p>

25 <p><strong>Step 2:</strong>29 ÷ 3 = 9.66 (remainder ≠ 0)</p>

27 <p><strong>Step 3:</strong>29 ÷ 5 = 5.8 (remainder ≠ 0) Since no divisors are found, 29 is a prime number. -</p>

27 <h2><strong>By Prime Factorization Method:</strong></h2>

29 <p>The Prime factorization method is the process of breaking down a<a>composite number</a>into the<a>product</a>of its<a>prime factors</a>. The method of prime factorization helps to identify the prime numbers up to 101 by building the smallest blocks of any given number. For example: The prime factorization of 100: Let's break it down into the smallest prime numbers until it can’t divide anymore.</p>

For example: The prime factorization of 100: Let's break it down into the smallest prime numbers until it can’t divide anymore.</p>

30 <p><strong>Step 1:</strong>100 ÷ 2 = 50</p>

29 <p><strong>Step 1:</strong>100 ÷ 2 = 50</p>

31 <p><strong>Step 2:</strong>Now, divide 50, 50 ÷ 2 = 25</p>

30 <p><strong>Step 2:</strong>Now, divide 50, 50 ÷ 2 = 25</p>

32 <p><strong>Step 3:</strong>Now take 25, since 25 ends in 5, divide the number by 5 25 ÷ 5 = 5</p>

31 <p><strong>Step 3:</strong>Now take 25, since 25 ends in 5, divide the number by 5 25 ÷ 5 = 5</p>

33 <p><strong>Step 4:</strong>At last, take 5. 5 ÷ 5 = 1 (since 5 is a prime number, and dividing by 5 gives 1)</p>

32 <p><strong>Step 4:</strong>At last, take 5. 5 ÷ 5 = 1 (since 5 is a prime number, and dividing by 5 gives 1)</p>

34 <p>Therefore, the prime factorization of 100 is: 100 = 2² × 5².</p>

33 <p>Therefore, the prime factorization of 100 is: 100 = 2² × 5².</p>

41 <p>The method, sieve of Eratosthenes, is an ancient algorithm used to find all prime numbers up to a given limit. First, we list all the numbers from 1 to 101. Then start with the first prime number, 2. Mark all the<a>multiples</a>of 2 as non-prime. Repeat the process for the next unmarked prime number and continue until you reach the<a>square</a>root of 101, approximately 10. The remaining unmarked numbers are the prime numbers. plain_heading7</p>

49 <h3>Problem 1</h3>

50 <p>Is 97 a prime number?</p>

51 <p>Okay, lets begin</p>

52 <p>Yes, 97 is a prime number.</p>

53 <h3>Explanation</h3>

54 <p>The square root of 97 is √97 ≈ 9.8, we check divisibility by primes less than 9.8 (2, 3, 5, 7).</p>

55 <p>97 ÷ 2 = 48.5</p>

56 <p>97 ÷ 3 = 32.33</p>

57 <p>97 ÷ 5 = 19.4</p>

58 <p>97 ÷ 7 = 13.857</p>

59 <p>Since 97 is not divisible by any of these numbers, 97 is a prime number.</p>

62 <p>A puzzle asks for the sum of the largest prime number less than 100. What is the number?</p>

63 <p>Okay, lets begin</p>

64 <p>97 is the largest prime number less than 100.</p>

65 <h3>Explanation</h3>

66 <p>Prime numbers are natural numbers that are greater than 1 and have no divisors other than 1 and the number itself.</p>

67 <p>The prime numbers under 100 are 2, 3, 5, 7, 11, 13, and so on.</p>

68 <p>97 is the largest prime number less than 100, therefore it is the number you're looking for.</p>
