A composite number is a positive integer which has a positive divisor other than one or itself. In other words, if 0 < n is an integer and there are integers 1 < a, b < n such that n = a × b then n is composite. By definition, every integer greater than one is either a Prime number or a composite number. The number one is a unit - it is neither prime nor composite. For example, the integer 14 is a composite number because it can be factored as 2 × 7.

Prime numbers have only two factors: one and themselves. By definition, your product would have more than that: one, the product and at least the two numbers that created the product. It has to be composite.

I believe it is. A composite number is a number that is the product of two other numbers multiplied, isn't it?

For any integer greater than 5, where the units digit is 5 then that number can be expressed as the product of n and 5. As such, the number is composite. Therefore all numbers in the range 150 to 200 that have a units digit of 5 are composite,.

Some. Any product of a set of odd numbers will be odd. To be even, a composite number must have at least one even factor. Therefore odd composite numbers must exist.

38 is a composite number because composite numbers are numbers that have more than 1 and themselves as factors. 1x38 is not the only solution, so it isn't prime. One solution for this could be 2x19
