3 <p>A number is classified as a prime number if it satisfies a certain condition. The number has to be having only two factors 1 and the number itself, all other numbers which have more than two factors are categorized under composite numbers. The prime are used in our everyday life for the security and pin encryption and in machinery building.</p>

4 <h2>Is 407 a prime number?</h2>

5 <p>A<a>prime number</a>should not have<a>factors</a>more than 2 but 407 has 4 divisors. No, 407 is a<a>composite number</a>. </p>

6 <p>The divisors<a>of</a>407 are1, 11, 37, and 407. Therefore, 407 is a composite number. Composite numbers are the numbers which have factors more than 2.</p>

8 <h2>Why is 407 a prime number?</h2>

9 <p>A<a>number</a>to be a prime number should follow the criteria, which is that it should not have factors more than 2. 407 has factors more than 2, so it is a composite number.</p>

10 <p>Given below are a few ways that can be used to find prime or composite numbers. </p>

11 <h3>Using the Counting Divisors Method</h3>

12 <p>In this method, the divisors of a number are listed, and the number is checked, to be called a prime number. The counting divisors method for 407 would simply be</p>

13 <p>Divisors of 407=1, 11, 37, 407.</p>

14 <p>Number of divisors = 4</p>

15 <p>The number 407 can be considered composite.</p>
