Question

Given that H.C.F. (306, 657) = 9, the L.C.M. (306, 657) is 22,332.

• A. 21023
• B. 19475

Answer 1

The correct option is B

19475

H.C.F.(306, 657)=9 means H.C.F. of 306 and 657= 9
Required L.C.M.(306, 657) means required L.C.M. of 306 and 657
For any two positive integers;
Their L.C.M. = $\frac{Productofthetwonumbers}{TheirH.C.F.}$
i.e., L.C.M.(306,657)=$\frac{306\times 657}{9}=22,338$
Hence it is false as the LCM is 22,338 and not 22,332
