Answer 2

Answer:

The HCF of 8, 24, and 40 is 8.

Step-by-step explanation:

Given: The numbers are 8, 24, and 40.

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 8, 24, and 40.

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

The factors of 8 are: $1, 2, 4, 8$

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

The factors of 40 are: $1, 2, 4, 5, 8, 10, 20, 40$

From the above, we can see that 8 is the highest number among all the common factors of the given numbers.

So, the greatest common factor(HCF) is 8.
