Factor Tree of 729

Given number is 729
The factor tree of 729 is as follows:

	729
3		243
	3		81
		3		27
			3		9
				3		3

729 = 3 x 243

243 = 3 x 81

81 = 3 x 27

27 = 3 x 9

9 = 3 x 3

If we write into multiples it would be 729 x 3

On splitting 243 further and writing it as multiples of numbers it would be 81 x 3.

On splitting 81 further and writing it as multiples of numbers it would be 27 x 3.

On splitting 27 further and writing it as multiples of numbers it would be 9 x 3.

On splitting 9 further and writing it as multiples of numbers it would be 3 x 3.
