Called 'factors', the whole numbers that go into 40 evenly are: 1, 2, 4, 5, 8, 10, 20, 40.
There is an infinity of such numbers: 8000000 is one, for example.
1, 2, 4, 5, and 10 can go into 20.
A single number, 20, does not have a lowest common multiple! So there are no two numbers to go in.
Not all numbers between 20 and 28 are composite numbers. 23 is a prime number.
