Any number whose digits add up to a multiple of 9 are divisible by 9, so there are many many possible combinations you can use. For example:
234
243
324
342
432
495
459
and so on...
Exactly 50
293 is not divisible by 5. Only numbers that end on 0 or 5 are exactly divisible by 5.No, it is not.
Any multiples of 4 including itself is divisible by 4
There are 2,966 numbers between 100 and 9,000 that are divisible by three.
There are 98 numbers are between 1 and 100 that are divisible by five.
There are 5 such numbers.
20 of them.
Exactly 50
1, 2, 4, 5, and 10
9 of them.
293 is not divisible by 5. Only numbers that end on 0 or 5 are exactly divisible by 5.No, it is not.
There are (500-100)/2 = 200 numbers divisible by 2 between 100 and 500 counting 100 but not 500. Of these (500-100)/8 = 50 are divisible by 8. So there are 150 numbers between 100 and 500 divisible by two but not by 8. By relative primeness exactly 50 out of these 150 are divisible by 3 and therefore these 50 are exactly the ones divisible by 6 but not by 8.
The smallest number which is exactly divisible by the numbers 8 9 and 10 is 360.
No.
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.

No - numbers are only divisible exactly by ten - if they end in a zero !
