Answer 2

Answer:

The HCF of 90 and 108​ is 18.

Step-by-step explanation:

Given: The numbers are 90 and 108​.

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 90 and 108​.

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

The factors of 90 are: $1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90$

The factors of 108 are: $1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108$

From the above, we can see that 18 is the highest number among all the common factors of the given numbers.

So, the greatest common factor(HCF) is 18.
