Factor Tree of 720

Given number is 720
The factor tree of 720 is as follows:

	720
2		360
	2		180
		2		90
			2		45
				3		15
					3		5

720 = 2 x 360

360 = 2 x 180

180 = 2 x 90

90 = 2 x 45

45 = 3 x 15

15 = 3 x 5

If we write into multiples it would be 720 x 2

On splitting 360 further and writing it as multiples of numbers it would be 180 x 2.

On splitting 180 further and writing it as multiples of numbers it would be 90 x 2.

On splitting 90 further and writing it as multiples of numbers it would be 45 x 2.

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.
