## What is the easiest way to find a prime number?

To prove whether a number is a prime number, first try dividing it by 2, and see if you get a whole number. If you do, it can’t be a prime number. If you don’t get a whole number, next try dividing it by prime numbers: 3, 5, 7, 11 (9 is divisible by 3) and so on, always dividing by a prime number (see table below).

**What is the prime factorization of the number 232?**

It can also be written in exponential form as 2 3 x 29 1 . Another way to do prime factorization is to use a factor tree. Below is a factor tree for the number 232.

**How are two prime numbers related to each other?**

Two prime numbers are always coprime to each other. Each composite number can be factored into prime factors and individually all of these are unique in nature. A prime number has two factors only. A composite number has more than two factors. It can be divided by 1 and the number itself. For example, 2 is divisible by 1 and 2.

### Is there a limit to the number of prime numbers?

Test for a prime number for any integer, or whole number, less than 10,000,000,000,000 (less than 10 trillion or a maximum of 13 digits). What is a Prime Number? A prime number is any integer, or whole number, greater than 1 that is only divisible by 1 and itself. In other words, a prime number only has two factors, 1 and itself.

### Which is the only prime number that is always coprime?

Every even positive integer greater than 2 can be expressed as the sum of two primes. Except 2, all other prime numbers are odd. In other words, we can say that 2 is the only even prime number. Two prime numbers are always coprime to each other.
