Answer 2

Answer:

The HCF of 121 and 55​​​ is 11.

Step-by-step explanation:

Given: The numbers are 121 and 55​​.

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 121 and 55​​.

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

The factors of 55 are: $1, 5, 11, 55$

The factors of 121 are: $1, 11, 121$

From the above, we can see that 11 is the highest number among all the common factors of the given numbers.

So, the greatest common factor(HCF) is 11.
