Given number is 2170
The factor tree of 2170 is as follows:
| 2170 | ||||||||||
| 2 | 1085 | |||||||||
| 5 | 217 | |||||||||
| 7 | 31 | |||||||||

2170 = 2 x 1085
1085 = 5 x 217
217 = 7 x 31
If we write into multiples it would be 2170 x 2
On splitting 1085 further and writing it as multiples of numbers it would be 217 x 5.
On splitting 217 further and writing it as multiples of numbers it would be 31 x 7.
Here are examples of Factor tree calculations.
