Answer 2

Answer:

The HCF of 20, 22, and 56 will be 2.

Step-by-step explanation:

Given: The numbers are 20, 22, and 56.

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 20, 22, and 56.

The HCF of the above numbers will be:

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

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

The factors of 22 are: $1, 2, 11, 22$

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

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

Therefore the greatest common factor(HCF) is 2.
