Answer 2

• HCF(108, 120) = 12

Given:

The two number 108 and 120

To find:

The HCF of the given number

Now,

First, we will do prime factorization, we will get

108 = 2 * 2 * 3 * 3 * 3 = 2² * 3³

120 = 2 * 2 * 2 * 3 * 5 = 2³ * 3 * 5

[Some points (easy method)]

• To find the HCF of two numbers choose the common number in both the number then select the lowest power of the common number.

So,

HCF(108, 120) = 2² * 3 = 4 * 3 = 12

More Information

• To find LCM, do prime factorization first. Then choose the common number and select the highest power of the selected common number. Also, multiply the numbers which are left.
