3 <p>Prime numbers are natural numbers greater than 1 with only two factors: 1 and the number itself. They play a crucial role in various fields, such as cryptography, digital security, and more. In this topic, we will explore prime numbers from 1 to 1,000,000.</p>

4 <h2>Prime Numbers 1 to 1000000</h2>

5 <p>A<a>prime number</a>is a<a>natural number</a>that has no positive divisors other than 1 and itself. Here are some key properties<a>of</a>prime numbers: </p>

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

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

8 </ul><ul><li>Every even<a>positive integer</a>greater than 2 can be expressed as the<a>sum</a>of two prime numbers (Goldbach's conjecture). </li>

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

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

26 <p>29 ÷ 5 = 5.8 (not divisible)</p>

25 <p>29 ÷ 5 = 5.8 (not divisible)</p>

27 <p>Since no divisors are found, 29 is a prime number.</p>

32 <p>25 ÷ 5 = 5 </p>

31 <p>25 ÷ 5 = 5 </p>

33 <p>5 ÷ 5 = 1</p>

32 <p>5 ÷ 5 = 1</p>

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

44 <h3>Problem 1</h3>

45 <p>Is 104729 a prime number?</p>

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

47 <p>Yes, 104729 is a prime number.</p>

48 <h3>Explanation</h3>

49 <p>The square root of 104729 is approximately 323.7. Check divisibility by primes less than 323.7. (2, 3, 5, 7, 11, ..., 317).</p>

50 <p>104729 ÷ 2 = 52364.5</p>

51 <p>104729 ÷ 3 = 34909.67</p>

52 <p>104729 ÷ 5 = 20945.8</p>

53 <p>104729 ÷ 7 = 14961.29</p>

54 <p>104729 ÷ 11 = 9511.73</p>

55 <p>Since 104729 is not divisible by any of these numbers, it is a prime number.</p>

57 <h3>Problem 2</h3>

58 <p>Alex is trying to open a digital locker with a 6-digit number. The code is the largest prime number under 1,000,000. Which prime number will open the lock?</p>

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

60 <p>The largest prime number under 1,000,000 is 999983.</p>

61 <h3>Explanation</h3>

62 <p>Prime numbers are natural numbers greater than 1 with no divisors other than 1 and themselves. In the range up to 1,000,000, 999983 is the largest prime number, hence it is the code for the digital locker.</p>

63 <p>Well explained 👍</p>

64 <h3>Problem 3</h3>

65 <p>A teacher challenges her students: Find the prime numbers that are closest to 100 but less than 100.</p>

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

67 <p>97 is the prime number closest to 100.</p>

68 <h3>Explanation</h3>

69 <p>97 is a prime number because it is only divisible by 1 and itself. The next prime number is 101, which is greater than 100. Therefore, the prime number closest to but less than 100 is 97.</p>
