Question

HCF of 1197,5320,4389.​

Answer 1

Answer:

The HCF of the given numbers is 133.

Step-by-step explanation:

Given: The numbers are 1197,5320,4389.

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 1197,5320,4389.​

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

The factors of 1197 are: $1, 3, 7, 9, 19, 21, 57, 63, 133, 171, 399, 1197$

The factors of 4389 are: $1, 3, 7, 11, 19, 21, 33, 57, 77, 133, 209, 231, 399, 627, 1463, 4389$

The factors of 5320 are: $1, 2, 4, 5, 7, 8, 10, 14, 19, 20, 28, 35, 38, 40, 56, 70, 76, 95, 133, 140, \\152, 190, 266, 280, 380, 532, 665, 760, 1064, 1330, 2660, 5320$

From the above, we can see that 133 is the largest positive integer that divides each of the integers.

Then the greatest common factor is 133.

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