​

Answer 1

$\huge{\bigstar{\underline{\sf{\blue{Answer}}}}}$

HCF of 18 & 60

18 = 2 x 3 x 3

60 = 2 x 2 x 3 x 5

HCF of 18 & 60 = 2 x 3

$\huge{\boxed{6}}$

Answer 2

Answer:

The HCF of 18 and 60 is 6.

Step-by-step explanation:

Given: The numbers are 18 and 60.

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 18 and 60.

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

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

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

From the above, we can see that 6 is the highest number among all the common factors of the given numbers.

So, the greatest common factor(HCF) is 6.
