Given number is 931
The factor tree of 931 is as follows:
| 931 | |||||||||
| 7 | 133 | ||||||||
| 7 | 19 | ||||||||

931 = 7 x 133
133 = 7 x 19
If we write into multiples it would be 931 x 7
On splitting 133 further and writing it as multiples of numbers it would be 19 x 7.
Here are examples of Factor tree calculations.
