Question

Product of two numbers is 2430. If their H.C.F is 9, find their L.C.M.

• A. 123
• B. 270
• C. 62
• D. 56

Answer 1

The correct option is B

270

Give that, Product of two numbers = 2430, H.C.F = 9

$\text{H.C.F}\times \text{L.C.M of any two numbers}=\text{Product of those numbers}$
$\therefore \text{L.C.M}=\frac{\text{Product of the given numbers}}{\text{Their H.C.F}}=\frac{2430}{9}=270$

Hence, the L.C.M is 270.
