Question

What is the HCF OF 31,37,33 by listing the factors

Answer 1

• As per data given in thequestion, We have to find the highest common factor of $31,37,33.$
• Step 1- Before solving this question we should know about the highest common factor.

       Highest common factor- This is the largest number that is a factor of

       two or more numbers. it is also called the greatest common factor.

• Step 2- We have to find factors among the three numbers.

        We will get it,

        $31=1\times 31,31\times 1.37=1\times 37,37\times 1.33=1\times 33,11\times 3,33\times 1.$

• Step 3- Then we observe the factors and find out the highest common factors among the three numbers.
• $1$ is the highest common factor.

       

Answer 2

Given: The numbers $31,37,33$

We have to find the HCF of the numbers  $31,37,33$

To calculate the HCF (Highest Common Factor) of $31,37, and 33$,

we need to factor each number and choose the highest factor that exactly divides the given numbers.

The factors of given numbers are;

$31=1*31\\=>1,33\\\\37=1*37\\=>1,37\\\\\\33=1*33 or 1*3*11\\=>1,3,11$

Hence, the HCF of $31,37,33$ is $1$.
