Factor Tree of 128

Given number is 128
The factor tree of 128 is as follows:

	128
2		64
	2		32
		2		16
			2		8
				2		4
					2		2

128 = 2 x 64

64 = 2 x 32

32 = 2 x 16

16 = 2 x 8

8 = 2 x 4

4 = 2 x 2

If we write into multiples it would be 128 x 2

On splitting 64 further and writing it as multiples of numbers it would be 32 x 2.

On splitting 32 further and writing it as multiples of numbers it would be 16 x 2.

On splitting 16 further and writing it as multiples of numbers it would be 8 x 2.

On splitting 8 further and writing it as multiples of numbers it would be 4 x 2.

On splitting 4 further and writing it as multiples of numbers it would be 2 x 2.
