Answer 2

Answer:

The HCF of 56, 84, and 15​ is 1.

Step-by-step explanation:

Given: The numbers are 56, 84, and 15​.

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 56, 84, and 15​.

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

The factors of 15 are: $1, 3, 5, 15$

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

The factors of 84 are: $1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84$

From the above, we can see that 1 is the highest number among all the common factors of the given numbers.

So, the greatest common factor(HCF) is 1.
