87 / 9 = 9.6 recurring (that is, 9.666... or 9 and two thirds). Therefore, 9 does not go evenly into 87.
1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54
Out of that list, 255 is evenly divisible by 3 and 5.
Technically, any number can be divided by any and all non-zero numbers, but I'll assume you mean evenly. There is no number that is evenly divisible by nine but not three because 9 is equal to 3x3. So when you divide by 9 it is the same as dividing by 3 twice.
To find five numbers with a mean of 10 and a range of 2, we first calculate the total sum of the five numbers, which would be 10 * 5 = 50. Since the range is 2, the numbers would need to be evenly spaced around the mean. One possible set of numbers could be 8, 9, 10, 11, and 12. These numbers have a mean of 10 and a range of 2.
Only the number one.
The lowest common multiple is 180
These are the whole numbers that go into 9 evenly: 1, 3, 9.
