Answer 2

Answer:

The HCF of 45 and 75 is 15.

Step-by-step explanation:

Given: The numbers are 45 and 75.

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 and 75.

The HCF of the above numbers will be:

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

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

The factors of 75 are: $1, 3, 5, 15, 25, 75$

From the above, we can see that 15 is the largest positive integer that divides each of the integers.

Therefore the greatest common factor(HCF) is 15.
