Answer:

composite no. =

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. ... For example, the integer 14 is a composite number because it is the product of the two smaller integers 2 × 7.

prime no. =

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.

co prime no.s =

In number theory, two integers a and b are said to be relatively prime, mutually prime, or coprime (also written co-prime) if the only positive integer (factor) that divides both of them is 1. Consequently, any prime number that divides one of a or b does not divide the other.

Answer:

Prime Numbers - these are numbers that are only divisible by themselves and 1. Examples: 2, 3, 5, 7, 11, 13.

Composite Numbers - these are not primes and so have divisors other than themselves and 1. Examples: 4=2x2, 6=2x3, 8=2x2x2.

Co-Prime Numbers - are pairs of numbers with no common factors (other than 1). Example: 15=3x5 and 16=2x2x2x2. Here, neither 15 nor 16 is a prime number, so they both have prime factors. However, none of the factors of 15 is a factor of 16, and vice-versa.
