A prime number (or a prime) is a natural number greater than 1 that cannot be formed by multiplying 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.However, 6 is composite because it is the product of two numbers (2 × 3) that
Get DetailsRelatively Prime. Describes two numbers for which the only common factor is 1. In other words, relatively prime numbers have a greatest common factor (gcf) of 1. For example, 6 and 35 are relatively prime (gcf = 1). The numers 6 and 8 are not relatively prime (gcf = 2).
Get DetailsOn the other hand, 21 and 9 are not relatively prime because you can divide both numbers by 3. As another example, -12 and -13 are relatively prime as the only numbers they can both be evenly divided by are 1 and -1 (having two divisors still makes the two numbers relatively prime).

Get DetailsThere is no basis to assume that divisibility by one prime number is anyhow related to the divisibility by any other prime number. We, therefore, assume that events of divisibility by prime numbers (or their complements) are independent such that the probability that two numbers are not simultaneously divisible by any prime should be the product:
