Question

What is the H.C.F of two numbers equal to?

• A. Product of the numbers their L.C.M
• B. Product of the numbers and their L.C.M
• C. Product of the numbers
• D. Quotient of the numbers

Answer 1

The correct option is A

Product of the numbers their L.C.M

The H.C.F of two numbers can be written as product of the numbers $÷$ L.C.M
For example, H.C.F of 60 and 72 can be written as:
60 $\times$ 72 $÷$ L.C.M
L.C.M of 60 and 72 is 360.
$\therefore$ $\frac{60\times 72}{360}$
$\Rightarrow$ $\frac{4320}{360}=12$
