Factor Tree of 1620

Given number is 1620
The factor tree of 1620 is as follows:

	1620
2		810
	2		405
		3		135
			3		45
				3		15
					3		5

1620 = 2 x 810

810 = 2 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 1620 x 2

On splitting 810 further and writing it as multiples of numbers it would be 405 x 2.

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.
