For example, the first 5 prime numbers are 2, 3, 5, 7, and 11. Increasing N to the value of 600, you will have enough primes. A good first guess is something in the order of 100log(100) 460 (coming from the prime number theorem). Note : I changed it from printing out just the numbers to appending the numbers to an array and then printing out the array. Prime numbers are numbers that have only 2 factors: 1 and themselves. Then just adjust N until you do have 100 primes. Prime numbers include large numbers and can continue well past 100. Now if you input a prime number it returns : Īnd any other number such as 20 : There are 25 prime numbers between 1 and 100. If is_prime(a)=True: #if the inputted number is prime it automatically appends that number to the list and breaks since prime numbers don't have any other factorsĭef remove_duplicates(values): #here it checks for duplicates #print(n) #otherwise it prints out the number since it is a prime number #print(n) #if one of the factors is 2 it prints it because it is a prime number Primes p that divide 2 n 1, for some prime number n. When you input a prime number it returns a blank array. If we run this and I input 10 it returns this : Print(n) #otherwise it prints out the number since it is a prime numberįor n in b: #iterates through the list of factors and checks if they are prime

If n % 2 = 0 or n <= 1: # if it is less than one or is a factor of 2 it returns false and does nothingįor divisor in range(3, sqr, 2): #checks for other divisors A natural number greater than 1 that is not a prime number is called a composite. In mathematics, a prime number is a natural number greater than 1 with no positive divisors other than 1. For example 2, 3, 5, 7.are prime numbers. Copy and Paste or Download a list of the prime numbers in many popular formats such as Excel, PDF, CSV, or Plain Text. Print(n) #if one of the factors is 2 it prints it because it is a prime number The number which is only divisible by itself and 1 is known as prime number. Instead of printing it you could also append it to another list by replace the print(n) with something else.

Here you can print the list of factors and then iterate through the list of factors and this program will print out the ones that are prime.
