Any number which does not follow this is termed as composite numbers which means that they can be factored into other positive integers. Subsets of the prime numbers may be generated with various formulas for primes. Here are the prime numbers in the range to 1000. Put another way, a prime number can be divided evenly only by and by itself.

In math, prime numbers are whole numbers greater thanthat have only two factors – and the number itself. In other words, a prime number only has two factors, and itself.

By contrast, numbers with more than factors are call composite numbers. Co- prime number is a set of numbers or integers which have only as their common factor i. It is important that there should be two numbers in order to form co-primes. How to Find Co- prime Numbers?

They are numbers (greater than 1) that are not prime. It is the product of two primes, and as a consequence of being an integer, also has the factors of and itself. If it is not evenly divided by any whole number other than or itself, the number is prime.
