That's an infinite list.
15, 30, 45, 60, 75, 90 and so on.
Which number is a factor of 10 , but not a multiple of 5
Any multiple of 15.
255
2,4,6,7,8,9,10,11,12,13,14,16,17,18,19,20........
15
30 is the smallest number that is a multiple of both 6 and 15
Such a number does not exist. 3600 is 60 squared and 4900 is 70 squared There is no number between 60 and 70 that is a multiple of 15 so there can be no square between 3600 and 4900 that is a multiple of 15.
15, 30, 45
15
It is 105
The only number between 15 and 25 that is a multiple of 57 is 0, as 57 itself is greater than 25. However, if you are looking for a number that is a multiple of 57 within that range, there is none. Therefore, there is no number between 15 and 25 that meets the criteria of being a multiple of 57.
The number 20 is.
