How to Find Prime Numbers?


Prime numbers are numbers that can be divided by 1 and itself. 1 is not a prime number since it is only divided by 1. It has to have only two factors. For example, 8 is not a prime number because it has more than two factors. We call this a composite number, which has more than two factors, which includes 1 and by itself as factors as well. There are infinite numbers of prime numbers or numbers that go on forever. Trying to choose which one is a prime number is like draining water from the pasta.
