Factor Tree of 3920

Given number is 3920
The factor tree of 3920 is as follows:

3920 = 2 x 1960

1960 = 2 x 980

980 = 2 x 490

490 = 2 x 245

245 = 5 x 49

49 = 7 x 7

If we write into multiples it would be 3920 x 2

On splitting 1960 further and writing it as multiples of numbers it would be 980 x 2.

On splitting 980 further and writing it as multiples of numbers it would be 490 x 2.

On splitting 490 further and writing it as multiples of numbers it would be 245 x 2.

On splitting 245 further and writing it as multiples of numbers it would be 49 x 5.

On splitting 49 further and writing it as multiples of numbers it would be 7 x 7.
