Factor Tree of 1215

Given number is 1215
The factor tree of 1215 is as follows:

	1215
3		405
	3		135
		3		45
			3		15
				3		5

1215 = 3 x 405

405 = 3 x 135

135 = 3 x 45

45 = 3 x 15

15 = 3 x 5

If we write into multiples it would be 1215 x 3

On splitting 405 further and writing it as multiples of numbers it would be 135 x 3.

On splitting 135 further and writing it as multiples of numbers it would be 45 x 3.

On splitting 45 further and writing it as multiples of numbers it would be 15 x 3.

On splitting 15 further and writing it as multiples of numbers it would be 5 x 3.
