Answer:

The HCF of the given numbers is 2.

Step-by-step explanation:

Given: The numbers are 6, 18, and 20.

We have to find the HCF of the above numbers.

• As we know that the greatest common divisor of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers.

We are solving in the following way:

We have,

The numbers are 6, 18, and 20.

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

The factors of 6 are: $1, 2, 3, 6$

The factors of 18 are: $1, 2, 3, 6, 9, 18$

The factors of 20 are: $1, 2, 4, 5, 10, 20$

From the above, we can see that 2 is the largest positive integer that divides each of the integers.

Then the greatest common factor is 2.

In this problem, we are assuming we have to find the HCF of the given numbers.
