Answer 2

Answer:

The HCF of the given numbers is 5.

Step-by-step explanation:

Given: The numbers are 45, 70, and 120.

We have to find the HCF of the above numbers.

• As we know that the greatest common divisor of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers.

We are solving in the following way:

We have,

The numbers are 45, 70, and 120.

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

The factors of 45 are: $1, 3, 5, 9, 15, 45$

The factors of 70 are: $1, 2, 5, 7, 10, 14, 35, 70$

The factors of 120 are: $1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120$

From the above, we can see that 5 is the largest positive integer that divides each of the integers.

Then the greatest common factor(HCF) is 5.

In this problem, we are assuming we have to find the HCF of the given numbers.
