6, 6, 3, 3, and 3

63,363
36,336

I just kept switching around the numbers till the sixes were separated by a factor of 1,000. This means that if the 6 is in a place, that if you multiply the 6 by 1,000, you'll get the place that the other 6 is in.

For 63,363, there is one 6 in the tens place and one in the ten thousands place. 60 x 1,000 = 60,000, which is where the first 6 is in. They are separated by x1,000. 

For 36,336, there is a 6 in the ones place and a 6 in the thousands place. 6 x 1,000 = 6,000, and there is a 6 in the thousands place. They are separated by x1,000.

(Hope the explanation helped!)
