Question

HCF of 11, 13, 31 HCF of 11 ,13 ,31

Answer 1

11 - 1 , 11

13 - 1 , 13

31 - 1 , 31

HCF = 1

Answer 2

In this problem, we are assuming we have to find the HCF of the numbers$11, 13,\ and\ 31$.

Q. Find the HCF of$11, 13,\ and\ 31$.

Given: The numbers are$11, 13,\ and\ 31$.

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$11, 13,\ and\ 31$.

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

The factors of 11 are:$1, 11$

The factors of 13 are:$1, 13$

The factors of 31 are: $1, 31$

Then the greatest common factor is$1$.

Hence, we get$HCF=1$.
