Composite of 2,23,37,42

Well there would not be any composite numbers to these because tin order for their to be a composite number you would have to have a positive number that it can be multiplied by. The composite of 2 is 2 and since 23 and 37 is odd 2 can not go into it. So therefore there is not composite. But the composite for 2 and 42 is 2 and the 23 and 37 are prime numbers!
