Factor Tree of 138

Given number is 138
The factor tree of 138 is as follows:

	138
2		69
	3		23

138 = 2 x 69

69 = 3 x 23

If we write into multiples it would be 138 x 2

On splitting 69 further and writing it as multiples of numbers it would be 23 x 3.

Here are examples of Factor tree calculations.

• Factor Tree of 139
• Factor Tree of 140
• Factor Tree of 141
• Factor Tree of 142
• Factor Tree of 143

Here we are providing different methods to find the factors of the number 138. They are splitting numbers and prime factors.
