Answer 2

Answer:

The HCF of 270, 945, and 2175​ will be 15.

Step-by-step explanation:

Given: The numbers are 270, 945, and 2175​.

We have to find the HCF of the above numbers.

• For this, we will first find the factors of the above numbers.
• And then, the largest positive integer that divides each of the given integers will be the HCF of the above numbers.

We are solving in the following way:

We have,

The numbers are 270, 945, and 2175​.

The factors of the above numbers will be:

The factors of 270 are: $1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270$

The factors of 945 are: $1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945$

The factors of 2175 are: $1, 3, 5, 15, 25, 29, 75, 87, 145, 435, 725, 2175$

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

So, the greatest common factor(HCF) is 15.
