Answer:

The HCF of 63, 105, and 210 is 21.

Step-by-step explanation:

Given: The numbers are 63, 105, and 210.

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 63, 105, and 210.

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

The factors of 63 are: $1, 3, 7, 9, 21, 63$

The factors of 105 are: $1, 3, 5, 7, 15, 21, 35, 105$

The factors of 210 are: $1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210$

 From the above, we can see that 21 is the highest number among all the common factors of the given numbers.

So, the greatest common factor(HCF) is 21.
