Well, actually, I have never heard that it is all that importand to use a devisor of the printer dpi, what is reported to maintain the best image quality is resampling on a devisor. Like if you scanned at 2400 dpi and you need to reduce the size of the image resample at 1200, 800, or 600, etc. That is supposed to maintain edge sharpness, etc. the best. On the other hand resampling at odd vailues is supposed to reduce artifacts, etc. Etc:-)
