Given number is 1917
The factor tree of 1917 is as follows:
| 1917 | ||||||||||
| 3 | 639 | |||||||||
| 3 | 213 | |||||||||
| 3 | 71 | |||||||||

1917 = 3 x 639
639 = 3 x 213
213 = 3 x 71
If we write into multiples it would be 1917 x 3
On splitting 639 further and writing it as multiples of numbers it would be 213 x 3.
On splitting 213 further and writing it as multiples of numbers it would be 71 x 3.
