40 is divisible by 1, 2, 4, 5, 8, 10, 20, 40.
No number between 20 and 40 is divisible by all 4 numbers. The smallest number divisible by all 4 of those numbers is: 56
24, 30 and 36.
20 and 40
Any element of the set of numbers of the form 40*k, where k is an integer, is evenly divisible.
40 is divisible by 1, 2, 4, 5, 8, 10, 20, 40.
Numbers that are divisible by both 4 and 5 are multiples of the least common multiple of 4 and 5, which is 20. Therefore, numbers that are divisible by 4 and 5 are multiples of 20. In other words, any number that can be expressed as 20 multiplied by an integer (e.g., 20, 40, 60, 80, etc.) is divisible by both 4 and 5.

10, 20, 30, 40, 50
1234568 10 12 20 30 40 60
They are both divisible by 1, 2, 4, 5, 10, and 20.
80 is an even number, thus it is divisible by 2; 80/2 = 40. 40 is also even, so it too is divisible by 2; 40/2 = 20. The same applies to 20; 20/2 = 10, and to 10; 10/2 = 5. Since both 2 and 5 are prime numbers, the prime factorization of 80 is 24 X 5.
The divisors of 40: 1 | 2 | 4 | 5 | 8 | 10 | 20 | 40 (8 divisors)
All multiples of 20, which is an infinite number. The first 5 numbers are: 20, 40, 60, 80, 100.
