Well they are used for multipling dividing adding and subtraction
Prime numbers and composite numbers are not used in daily jobs. However they are used by scientists to prove theorems.
3 can be used.
There may not be any fast methods. In fact, composite numbers which are the product of two very large primes are used for public key encryption. This depends on the fact that there is no fast answer to factorising composite numbers.
Rectangular numbers are a subset of composite numbers. The squares of prime numbers will be composite but not rectangular.
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

Composite numbers can be used by businessmen, shopkeepers etc. These people use calculations a lot in their daily life.

Composite numbers are used to factorize a number into smaller. It makes calculation easy for the person.

Not all composite numbers are even, but all even numbers except 2 are composite.

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 :)
Actually it is composite numbers that are used - products of two very large primes.
Both are composite numbers
Only 63. 0 and 1 are not composite numbers and are not prime numbers (even though 1 used to be). 19 is a prime number.
