Factor Tree of 645

Given number is 645
The factor tree of 645 is as follows:

	645
3		215
	5		43

645 = 3 x 215

215 = 5 x 43

If we write into multiples it would be 645 x 3

On splitting 215 further and writing it as multiples of numbers it would be 43 x 5.

Here are examples of Factor tree calculations.

• Factor Tree of 650
