10 4 7 10 (Posted on 2015-11-03) Difficulty: 3 of 5
Consider decimal number 33. If converted to base 4 form it would be 201, which if regarded as 7 base number would yield 99 decimal.
Pay attention: 99=3*33.
219 is another number displaying the same feature (when converted to base 4 and interpreted as base 7 creates a multiple of the original decimal number).

Please list some additional samples.
