To find the numbers between 20 to 50 that are divisible by 3, we need to determine the first and last numbers in that range that are divisible by 3. The first number divisible by 3 is 21, and the last number divisible by 3 is 48. To find the total count of numbers divisible by 3, we can use the formula (last number - first number) / 3 + 1 = (48 - 21) / 3 + 1 = 8. Therefore, there are 8 numbers between 20 to 50 that are divisible by 3.
20 of them.

20 if you include 100, 19 if you don't.
Remember 1 is not a prime number because it is only divisible by itself. 2, 3, 5, 7, 11, 13, 17, 19 These are the prime numbers between 0 and 20. In short, there are 9 prime numbers between 0 and 20.
There are 69 odd numbers between 20 and 158.
Nine of them are evenly divisible by 5, if you include 20 and 60.

There are 9 numbers evenly divisible by 10 : 10, 20, 30, 40, 50, 60, 70, 80, and 90
To be divisible by both 4 and 5, the number has to be divisible by 20. Therefore, there are 12 numbers between 1 and 240, inclusive, which are divisible by 4 and 5: 20, 40, 60, 80, 100, 120, 140, 160, 180, 200, 220, 240.
