What is a prime number?

A prime number is a positive integer greater than 1 that can only be divided by 1 and itself without resulting in a remainder. In other words, a prime number has exactly two distinct positive divisors: 1 and the number itself.

Give an example of a prime number.

One example of a prime number is the number 17. This is because 17 is only divisible by 1 and itself, making it a prime number.

What is a composite number?

A composite number is a positive integer greater than 1 that can be formed by multiplying two smaller positive integers together, other than 1 and itself. In other words, it has at least one factor other than 1 and itself. Examples of composite numbers include 4, 6, 8, 10, and so on.

Provide an example of a composite number.

An example of a composite number is 24.

How can you determine if a number is prime or composite?

To determine if a number is prime or composite, you need to check if it has factors other than 1 and itself. Start by dividing the number by all integers up to its square root. If the number has a factor other than 1 and itself, then it is composite. If it only has 1 and itself as factors, then it is prime. Prime numbers are only divisible by 1 and themselves, while composite numbers have multiple factors.

Is 1 a prime or composite number? Why?

1 is neither a prime nor a composite number. Prime numbers are defined as numbers greater than 1 that have only two factors: 1 and themselves. Since 1 only has one factor (itself), it does not meet the criteria to be considered a prime number. Additionally, composite numbers are defined as numbers greater than 1 that have more than two factors. Since 1 only has one factor, it also does not meet the criteria to be considered a composite number.

Can prime numbers be negative? Give a reason.

No, prime numbers cannot be negative. By definition, prime numbers are natural numbers greater than 1 that have only two distinct positive divisors: 1 and the number itself. Therefore, prime numbers must be positive integers.

Are all even numbers composite? Explain why or why not.

No, not all even numbers are composite. An even number is defined as a number that is divisible by 2. While most even numbers are composite (meaning they have factors other than 1 and themselves), there is one exception - the number 2. The number 2 is the only even prime number, as it is only divisible by 1 and itself. All other even numbers greater than 2 are composite because they can be expressed as the product of at least two positive integers other than 1 and itself.

What is the difference between prime and composite numbers?

Prime numbers are whole numbers greater than 1 that have only two factors: 1 and the number itself. Composite numbers, on the other hand, are whole numbers greater than 1 that have more than two factors, meaning they can be divided by other numbers besides just 1 and themselves.

Why are prime numbers important in the field of mathematics?

Prime numbers are important in mathematics because they are the building blocks of all natural numbers and play a crucial role in number theory. Prime numbers have unique properties that make them essential in various mathematical algorithms, cryptography, and computer science. Their distribution and characteristics have been a subject of study for centuries, leading to many important discoveries and advancements in the field of mathematics.
