To find the number of integers from 1 to 500 that are divisible by 7, we need to determine the number of multiples of 7 within this range. The first multiple of 7 in this range is 7, and the last multiple is 497. To find the count, we divide the last multiple by 7 and subtract the first multiple divided by 7, then add 1 (to include the first multiple). So, 497/7 - 7/7 + 1 = 71 - 1 + 1 = 71. Therefore, there are 71 integers from 1 to 500 that are divisible by 7.

Determine the number of integers between 1 to 250 that are divisible by any of the integer 2 or 3 or 5 or 7?
There are 193 numbers in between 1 and 250 that are divisible by 2, 3, 5, or 7. Note that if you are not including 250 (so if you meant 1 - 249), then there are 192.
How many integers between 1 and 1000 inclusive are divisible by 6 or 21 but not by 7?
Oh, dude, let me break it down for you. So, first, you find how many numbers are divisible by 6, which is 166. Then you find how many are divisible by 21, which is 47. But wait, don't forget to subtract the ones divisible by both 6 and 21, which is 7. So, the total is 166 + 47 - 7 = 206 integers that fit the bill. Easy peasy!
