1, 3, 5, 9, 15, 25, 45, 75, 225.
Since 225 is an odd number, it is impossible to divide it by 4 without leaving a remainder.
The answer depends on what you wish to do with the estimate. If you wanted to divide by 3, I would suggest 225 since 225/3 = 75. If you wanted to divide by 4 I would suggest 224 or 228 [/4 = 56 or 57]. If dividing by 5 I would suggest 225 again since 225/5 = 45.
