Answer 2

Answer:

The HCF of 728 and 16​​ is 8.

Step-by-step explanation:

Given: The numbers are 728 and 16​.

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 728 and 16​.

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

The factors of 16 are: $1, 2, 4, 8, 16$

The factors of 728 are: $1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728$

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.
