What is a prime number?

A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. In other words, a prime number is a number that is only divisible by 1 and itself, and does not have any other factors.

Can the number 1 be considered a prime number? Why or why not?

No, the number 1 cannot be considered a prime number. By definition, a prime number is a whole number greater than 1 that is divisible by only 1 and itself. Since 1 does not meet this criteria as it is only divisible by 1, it is not classified as a prime number.

How is a prime number different from a composite number?

A prime number is a number greater than 1 that has only two factors: 1 and itself, whereas a composite number has more than two factors, including 1 and itself. In other words, prime numbers can only be divided by 1 and themselves evenly, while composite numbers can be divided by multiple numbers other than 1 and the number itself.

What is the smallest prime number?

The smallest prime number is 2.

Are prime numbers only divisible by 1 and themselves? Provide an example.

Yes, prime numbers are only divisible by 1 and themselves. An example is the number 11, which can only be divided by 1 and 11 without leaving a remainder.

How many prime numbers are there between 1 and 10?

There are four prime numbers between 1 and 10, which are 2, 3, 5, and 7.

What is the largest prime number less than 100?

The largest prime number less than 100 is 97.

Is it possible for a prime number to end in an even digit? Why or why not?

No, it is not possible for a prime number to end in an even digit, except for the number 2. This is because all prime numbers greater than 2 are odd. An even digit at the end of a number indicates that the number is divisible by 2, making it non-prime.

Are prime numbers commonly used in encryption algorithms? Explain why or why not.

Yes, prime numbers are commonly used in encryption algorithms, specifically in public-key cryptography. This is because prime factorization, which is the process of breaking down a number into its prime factors, is computationally complex and difficult to reverse. By using large prime numbers in encryption algorithms, it becomes extremely challenging for hackers to decrypt the encrypted data without possessing the private key. This ensures the security and confidentiality of information being transferred over public networks.

How are prime numbers related to factorization and the Fundamental Theorem of Arithmetic?

Prime numbers are essential in factorization and the Fundamental Theorem of Arithmetic. Prime numbers are the building blocks of all positive integers, as every positive integer can be uniquely represented as a product of prime numbers (prime factorization). The Fundamental Theorem of Arithmetic states that every positive integer greater than 1 can be expressed as a unique product of prime numbers, confirming the importance of prime numbers in factorization. This theorem highlights the role of prime numbers as the foundational elements in the world of integer mathematics, providing a crucial link between prime numbers, factorization, and the unique decomposition of positive integers into their prime factors.
