Prime numbers7/13/2023 Let us learn about the Sieve of Eratosthenes in the following section. This method is called the Sieve of Eratosthenes. He designed a smart way to determine all the prime numbers up to a given number. ![]() Euclid proposed the theorem on prime numbers - there are infinitely many prime numbers.ĭo you know all the prime numbers from 1 to 100? Did you check if each number is divisible by the smaller numbers? Eratosthenes was one of the greatest scientists who lived a few decades after Euclid. Even today, mathematicians are trying to find prime numbers with mystical properties. Prime numbers have created human curiosity since ancient times. This means the list of odd numbers can start from 3 onwards and continue because the rest of the prime numbers are odd numbers. Interestingly, 2 is the only prime number that is even. It should be noted that all prime numbers are odd numbers except for the number 2 which is an even number. It should be noted that Co-prime numbers need not necessarily be prime numbers.Ī few examples of prime numbers are 2, 3, 5, 7, and so on.Ī prime number chart is a chart that shows the list of prime numbers in a systematic order. We can see that they have only 1 as their common factor, therefore, they are coprime numbers. The factors of 18 are 1, 2, 3, 6, 9 and 18 and the factors of 35 are 1, 5, 7 and 35.
