Answer 2

Answer:

The HCF of 390 and 468 is 78.

Step-by-step explanation:

The numbers are 390 and 468.

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 390 and 468.

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

The factors of 390 are: $1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390$

The factors of 468 are: $1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468$

From the above, we can see that 78 is the highest number among all the common factors of the given numbers.

So, the greatest common factor(HCF) is 78.
