This is because the multiples can have more than two factors.

Multiples of a number except 1 are not prime numbers.

If a number has more than two factors (1 and itself), then it is not a prime number.

Any other number that has 0, 2, 4, 6, or 8 as the last digit is not a prime number since they are completely divisible by 2.

From prime numbers 1 to 500, 2 is the only even prime number.

Important Notes on Prime Numbers 1 to 500 These prime numbers can be segregated in the range of numbers as shown in the following table. All the numbers that are listed in the table have exactly 2 factors. There are 95 prime numbers between 1 and 500 as shown below. The prime numbers from 1 to 500 are listed in the following chart.

Step 3: If step 2 is not successful, the number will not be considered as a prime number.

Step 2: If there are only two factors, add them to the list of prime numbers from 1 to 500. Step 1: List down the factors of all the numbers from 2 to 500 (Exclude 1 as it is not a prime or a composite number)

The steps to use the factorization method to find the prime numbers from 1 to 500 are listed below. Therefore, it can be expressed as 1 × 19 or 19 × 1. From this, it is evident that 15 is not a prime number, whereas the number 19 has only two factors, which are 1 and 19. In other words, 15 can be expressed by the following multiplication facts: 1 × 15, 3 × 5. For example, the number 15 has 1,3,5 and 15 as its factors.

If there are no other factors other than 1 and the number itself, then it can be termed as a prime number, otherwise, it is a composite number. In the factorization method, we check to see if a number has more than 2 factors, other than 1, and the same number. The following method shows how to check if a number is prime or not. There are 95 prime numbers from 1 to 500. Prime numbers from 1 to 500, have exactly 2 factors. The numbers that have more than two factors are called composite numbers. A prime number is always divisible by 1 and the number itself. In order to find the prime numbers between 1 and 500, we need to know the factors of all the numbers within this range.
