Answer:
Prime number: A number that can only be divided by 1 and itself. For example 7, 11, etc
Odd number. Any number that cannot be divided by 2. For example 3, 5, 7, etc
Even number: Any number than can be divided by 2. For example: 4, 6, 8, etc
Composite number: This is the exact opposite of a prime number. A composite number can be divided by 1, itself, and some other number. For example: 15. Can be divided by 1, itself, 3 and 5.
Also 4. Can be divided by 1, itself, and 2.
Please note. All of the definitions above refer to divisions without remainders.
Answer:
A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself
A composite number is a positive integer that can be formed by multiplying two smaller positive integers. Equivalently, it is a positive integer that has at least one divisor other than 1 and itself.
Two numbers or integers are co-prime if their common factor is only 1. There should be a minimum of two numbers to form a set of coprime numbers. Such numbers have only 1 as their highest common factor, for example, {4 and 7}, {5, 7, 9} are coprime numbers. Co-prime numbers need not be prime numbers always.
Common Factor: 1
Factors: 1,2,7,1
A twin prime is a prime number that is either 2 less or 2 more than another prime number—for example, either member of the twin prime pair (41, 43). ... However, it is unknown whether there are infinitely many twin primes (the so-called twin prime conjecture) or if there is a largest pair.
