3 <p>Prime numbers are natural numbers greater than 1 that have no divisors other than 1 and themselves. They are crucial in mathematics and have applications in fields like cryptography and computer science. In this topic, we will focus on the prime numbers between 101 and 150.</p>

4 <h2>Prime Numbers 101 to 150</h2>

5 <p>A<a>prime number</a>is a<a>natural number</a>that can only be divided by 1 and itself without leaving a<a>remainder</a>. Here are some fundamental properties of prime numbers:</p>

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

7 <p>Two distinct prime numbers are always<a>relatively prime</a>.</p>

8 <p>Every even<a>positive integer</a>greater than 2 can be expressed as the<a>sum</a>of two prime numbers, as per the Goldbach conjecture.</p>

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

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

24 <p><strong>By Divisibility Method:</strong></p>

26 <p>To determine whether a number is prime, check its divisibility. If a number is divisible by any other number besides 1 and itself, it is not prime. For example: To check whether 113 is a prime number,</p>

25 <p>To determine whether a number is prime, check its divisibility. If a number is divisible by any other number besides 1 and itself, it is not prime. For example: To check whether 113 is a prime number,</p>

27 <p><strong>Step 1:</strong>113 ÷ 2 = 56.5 (not divisible)</p>

26 <p><strong>Step 1:</strong>113 ÷ 2 = 56.5 (not divisible)</p>

28 <p><strong>Step 2:</strong>113 ÷ 3 ≈ 37.67 (not divisible)</p>

27 <p><strong>Step 2:</strong>113 ÷ 3 ≈ 37.67 (not divisible)</p>

29 <p><strong>Step 3:</strong>113 ÷ 5 = 22.6 (not divisible)</p>

28 <p><strong>Step 3:</strong>113 ÷ 5 = 22.6 (not divisible)</p>

30 <p>Since no divisors are found, 113 is a prime number.</p>

31 <p>This method involves expressing a number as a<a>product</a>of its<a>prime factors</a>, which can help in identifying prime numbers. For example: The prime factorization of 144:</p>

33 <p><strong>Step 1:</strong>144 ÷ 2 = 72</p>

32 <p><strong>Step 1:</strong>144 ÷ 2 = 72</p>

34 <p><strong>Step 2:</strong>72 ÷ 2 = 36</p>

33 <p><strong>Step 2:</strong>72 ÷ 2 = 36</p>

35 <p><strong>Step 3:</strong>36 ÷ 2 = 18</p>

34 <p><strong>Step 3:</strong>36 ÷ 2 = 18</p>

36 <p><strong>Step 4:</strong>18 ÷ 2 = 9</p>

35 <p><strong>Step 4:</strong>18 ÷ 2 = 9</p>

37 <p><strong>Step 5:</strong>9 ÷ 3 = 3</p>

36 <p><strong>Step 5:</strong>9 ÷ 3 = 3</p>

38 <p><strong>Step 6:</strong>3 ÷ 3 = 1</p>

37 <p><strong>Step 6:</strong>3 ÷ 3 = 1</p>

39 <p>Therefore, the prime factorization of 144 is 2⁴ × 3².</p>

54 <h3>Problem 1</h3>

55 <p>Is 149 a prime number?</p>

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

57 <p>Yes, 149 is a prime number.</p>

58 <h3>Explanation</h3>

59 <p>The square root of 149 is approximately 12.2.</p>

60 <p>Check divisibility by primes less than 12.2 (2, 3, 5, 7, 11).</p>

61 <p>149 ÷ 2 = 74.5</p>

62 <p>149 ÷ 3 ≈ 49.67</p>

63 <p>149 ÷ 5 = 29.8</p>

64 <p>149 ÷ 7 ≈ 21.29</p>

65 <p>149 ÷ 11 ≈ 13.545</p>

66 <p>Since 149 is not divisible by any of these numbers, 149 is a prime number.</p>
