Since there are no other possible factors for these numbers, therefore, these are prime numbers. We can see that the above numbers have only two factors, 1 and the number itself. Let us cross-check any two prime numbers by finding out the possible factors of the number. Total prime numbers from 1 to 1000 = 168. Observe the list of prime numbers from 1 to 1000 given below.
Factors can be easily found with the help of the prime factorization method.
Therefore, by finding out the factors of a number we can find the prime numbers from 1 to 1000. It can be seen that 12 is not a prime number because it has more than two factors. The factors of 12 can be listed as, 1, 2, 3, 4, 6, and 12. For example, let us take the number 11 which has only two factors which are 1 and 11 itself. We know that a prime number is a number with only two factors, 1 and the number itself. The prime numbers from 1 to 1000 can be listed if we find out the number of factors of each number.
