The smallest composite numbers are 4, 6, 8, 9, and 10. It should be noted that the number 1 is a unit, and is neither prime nor composite. The numbers 2, 3, 5, and 7 are all prime, leaving the remaining numbers as the 5 smallest composites.
4 is the smallest composite number and it is not divisible by the two given numbers.
The least 1 digit number that is composite is 4. It is because all numbers before that are prime.
Smallest will be 10 Biggest will be 99

The least 1 digit number that is composite is 4. It is because all numbers before that are prime.
There are no such numbers. The smallest set of three consecutive composite numbers is {8, 9, 10} and the product of these numbers is 720.

No, some composite numbers are odd. The smallest composite odd numbers are 9, 15, 21, 25, and 27. Not all even numbers are composite either. There's only one even number that's prime, which is 2.

It is 2520.
If the number is a product of two composite numbers, it must be 16, which is the product of 4 and 4. The prime factors of 16 are 2, 2, 2, and 2. The smallest composite number is 4, so the smallest possible product of two composite numbers is 4 x 4 = 16.
99 - 2 = 97

Many prime numbers and many composite numbers.
