Eratosthenes
Eratosthenes' method of finding prime and composite number is called 'The Sieve of Eratosthene'.
finding the prime factors of a composite number
Yes, there is an infinite amount of prime numbers. This has been proven by the ancient Greek mathematician Euclid. As for composite numbers, since there are infinitely many natural numbers, there must also be an infinite amount of composite numbers, as they are all the natural numbers that are not prime.
he was great mathematician . he invented algebric numbers. in 19th and early 20th century

All composite numbers have prime factors and these are used to find the highest common factor of 2 or more numbers and they are also used in finding the lowest common multiple of 2 or more numbers. Composite numbers have 2 or more factors while prime numbers have only 2 factors which are themselves and one
Not all composite numbers are even, but all even numbers except 2 are composite.
Rectangular numbers are a subset of composite numbers. The squares of prime numbers will be composite but not rectangular.
composite numbers are those that have more than 2 factors. all even numbers other than 2 are composite numbers and some odd numbers are composite numbers. numbers that are prime are the numbers that are not composite numbers i hope this answers your question :)
To find out the difference between prime numbers and composite numbers because prime numbers are useful in finding the lowest common multiple of numbers or the highest common factor of numbers.
Both are composite numbers
30,32,33,34,35,36,38,39,40 are the composite numbers between 30 and 40. Composite numbers are numbers that are not prime numbers.
