Answer 2

Answer:

The HCF of 56 and 57​​​ is 1.

Step-by-step explanation:

Given: The numbers are 56 and 57​​​.

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 56 and 57.​

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

The factors of 56 are: $1, 2, 4, 7, 8, 14, 28, 56$

The factors of 57 are: $1, 3, 19, 57$

From the above, we can see that 1 is the highest number among all the common factors of the given numbers.

So, the greatest common factor(HCF) is 1.
