Answer 2

Answer:

The HCF of 2, 4, 5, and 7​ is 1.

Step-by-step explanation:

Given: The numbers are 2, 4, 5, and 7​.

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 2, 4, 5, and 7​.

The factors of 2 are: $1, 2$

The factors of 4 are: $1, 2, 4$

The factors of 5 are: $1, 5$

The factors of 7 are: $1, 7$

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.
