Question

If the L.C.M of two numbers 39 and 221 is 663, then the H.C.F of the numbers would be 13.

• A. True
• B. False

Answer 1

The correct option is A

True

Product of two numbers = L.C.M of the two numbers $\times$ H.C.F of the two numbers

$\Rightarrow$39 $\times$ 221= 663 $\times$ H.C.F

$\Rightarrow$8619 = 663 $\times$ H.C.F

$\Rightarrow$ H.C.F of the two numbers = $\frac{8619}{663}$

$\Rightarrow$$H.C.F=13$
