Do you really know all the prime numbers?
The way to know the Prime Numbers is to find out if they can only Multiplied Once ,The way to know Composite Numbers is to find out if they can be Multiplied Twice
Is there more composite numbers then prime and why?
Sieves of Eratosthenes is a good way to understand why: For example: Write down all numbers from 1 to 100 2 is prime, so all its multiple are composite, all even numbers except 2 are composite, so erase them. Half of the numbers are already erased 3 is prime, so all its multiple are composite, so erase them. A bit less than one third of the remaining number are erased (multiples of 6 have already been erased) 5 is prime, so all its multiple are composite, so erase them.... and so on with 7 and 11.... Each time a prime number is found all its multiples are to be erased from the list. Thus there are more composite numbers (erased ones) than primes.
What are prime and composite numbers and can you tell me in a easy way to understand?
Prime numbers have only 2 factors which are themselves and one whereas composite numbers have more than 2 factors
Is 5 a prime number or a composite numb?
5 is a prime number,because prime numbers only have too numbers that go into itself.those numbers are 1 and itself, in this case 5. with composite numbers it is the other way around.
What is the difference between composite numbers and prime numbers?
Prime numbers can only be represented in a multiplication problem by one times itself. Composite numbers can be represented in more than one way.2 is primes 1x24 is composite 1x4; 2x2Prime numbers have only two factors whereas composite number have more than two factors.A prime number is a positive integer with two factors: one and the number itself.A composite number is a positive integer with more than two factors.
