a prim number is a number that only one and its self can go it to it ....... And a composite number is when other numbers can go in to it
There are no two "last" composite numbers. Just as with prime numbers, and all numbers, they go on for ever and ever and ever and ever ... ... .
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 :)
175 is composite because it can be broken down into smaller numbers.
