To be divisible by 3 and 4 the number must be divisible by 12.
201/12 = 16.75 so the smallest number in the range, divisible by 12, is 17*12 = 204
301/12 = 25.08 so the largest number in the range, divisible by 12, is 25*12 = 300
The number of multiples of 12 is 25 - 16 = 9
between 1 and 600 inclusive there are:300 numbers divisible by 2200 numbers divisible by 3100 numbers divisible by both 2 and 3400 numbers divisible by 2 or 3.

111 numbers between 5 and 1000 are divisible by 9
Four. 24 and its multiples.
Oh, what a lovely question! Let's see, we can find the numbers divisible by 3 first, which are 33 numbers, and the numbers divisible by 7, which are 14 numbers. But wait, some numbers are divisible by both 3 and 7, so we must be careful not to count them twice. In the end, there are 47 numbers between 1 and 100 that are divisible by 3 or 7. Happy counting!
