Factor Tree of 140

Given number is 140
The factor tree of 140 is as follows:

	140
2		70
	2		35
		5		7

140 = 2 x 70

70 = 2 x 35

35 = 5 x 7

If we write into multiples it would be 140 x 2

On splitting 70 further and writing it as multiples of numbers it would be 35 x 2.

On splitting 35 further and writing it as multiples of numbers it would be 7 x 5.

Here are examples of Factor tree calculations.

• Factor Tree of 141
• Factor Tree of 142
• Factor Tree of 143
• Factor Tree of 144
• Factor Tree of 145

Here we are providing different methods to find the factors of the number 140. They are splitting numbers and prime factors.
