Answer 2

Answer:

The HCF of 648, 405, and 243​ is 81.

Step-by-step explanation:

Given: The numbers are 648, 405, and 243​.

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 648, 405, and 243​.

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

The factors of 243 are: $1, 3, 9, 27, 81, 243$

The factors of 405 are: $1, 3, 5, 9, 15, 27, 45, 81, 135, 405$

The factors of 648 are: $1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648$

From the above, we can see that 81 is the highest number among all the common factors of the given numbers.

So, the greatest common factor(HCF) is 81.
