Question

The product of two numbers is 2160 and their HCF is 12. The LCM of these numbers is

Options

• 12

• 25920

• 180

• none of these

Answer 1

180
Here, H.C.F. = 12
Product of two numbers = 2160 
We know:
L.C.M. × H.C.F. = Product of the two numbers

L.C.M. = \[\frac{2160}{\text{H.C.F.}}\]
= \[\frac{2160}{12}\]
= 180
L.C.M. = 180
