The simplest thing is to use the Sieve of Eratosthenes: write out the positive integers in order (as many as you like) and then starting with 2, circle 2, and then cross off every second number (4, 6, 8, etc.) Then find the next unmarked number (3) and circle it, and cross off every third number (6, 9, 12, etc.) then find the next unmarked number (5) and repeat the process over and over.

what are the numbers for not prime numbers?
Numbers that are not prime numbers are called composite numbers.
Why are prime numbers divisible?
Prime numbers are divisible because any numbers that are divisible are prime. If a number isn't divisible, it isn't prime. Prime numbers have to be divisible by at least one pair of numbers to be prime.
How do you learn numbers?
Prime numbers are any numbers that are only divisible by one, and itself. For example, 3 is prime because the only numbers that go into it are 3 and 1. 6 isn't prime because not only can 6 and 1 go into it, but 3 and two can as well.
How do you learn to do prime and composite numbers?
List their factors. Prime numbers have two factors, composite numbers have more than two.
What can you learn about composite and prime numbers?
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.

What are numbers that have 2 factors called?
Prime numbers like 2, 3, 5 and 7.
what are the numbers for not prime numbers?
Numbers that are not prime numbers are called composite numbers.
Are any two prime numbers relatively prime?
Any two prime numbers will be relatively prime. Numbers are relatively prime if they do not have any prime factors in common. Prime numbers have only themselves as prime factors, so all prime numbers are relatively prime to the others.
Why are prime numbers divisible?
Prime numbers are divisible because any numbers that are divisible are prime. If a number isn't divisible, it isn't prime. Prime numbers have to be divisible by at least one pair of numbers to be prime.
Are there infinitely many natural numbers that are not prime?
This can be an extension to the proof that there are infinitely many prime numbers. If there are infinitely many prime numbers, then there are also infinitely many PRODUCTS of prime numbers. Those numbers that are the product of 2 or more prime numbers are not prime numbers.
How do you memorise prime numbers?
There are infinitely many prime numbers so it is impossible to memorise them. Prime numbers do not follow any simple rule so it is not possible to memorise them by learning a rule either. Your best bet is to use them often so that you become familiar with them and so will recognise them. Also, learn the factorisation of odd numbers - since after 2, you need not bother with even numbers.
