Question

Given that $LCM(91,26)=182$, then $HCF(91,26)$ is:

• A. $13$
• B. $26$
• C. $7$
• D. $9$

Answer 1

The correct option is A $13$

We know that the product of $LCM$ and $HCF$ of two numbers is equal to the product of two numbers.

So $\Rightarrow HCF\times LCM=91\times 26$

$\Rightarrow 182\times HCF=2366$

$\Rightarrow HCF=13$

So the correct answer is option A
