Answer 2

Answer:

The HCF of 20, 48, and 120 is 4.

Step-by-step explanation:

Given: The numbers are 20, 48, and 120.

We have to find the HCF of the above numbers.

• As we know, the HCF (Highest Common Factor) of two or more numbers is the highest number among all the common factors of the given numbers.
• HCF is also known as the greatest common factor.

We are solving in the following way:

We have,

The numbers are 20, 48, and 120.

First, we will find the factors of the above numbers.

The factors of 20 are: $1, 2, 4, 5, 10, 20$

The factors of 48 are: $1, 2, 3, 4, 6, 8, 12, 16, 24, 48$

The factors of 120 are: $1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120$

From the above, we can see that 4 is the highest number among all the common factors of the given numbers.

So, the greatest common factor(HCF) is 4.
