Answer 2

Answer:

The HCF of 21, 60, and 27 is 3.

Step-by-step explanation:

Given: The numbers are 21, 60, and 27.

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 21, 60, and 27

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

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

The factors of 27 are:$1, 3, 9, 27$

The factors of 60 are: $1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60$

From the above, we can see that 3 is the largest positive integer that divides each of the given integers.

Therefore the greatest common factor(HCF) is 3.
