Given number is 638
The factor tree of 638 is as follows:
| 638 | |||||||||
| 2 | 319 | ||||||||
| 11 | 29 | ||||||||

638 = 2 x 319
319 = 11 x 29
If we write into multiples it would be 638 x 2
On splitting 319 further and writing it as multiples of numbers it would be 29 x 11.
Here are examples of Factor tree calculations.
