The HCF of two numbers 24 and their LCM is 216. If one of the number is 72, then the other number is
Let the number be $$a$$ and other number = $$b=72$$
We know that : $$H.C.F(a,b)\times L.C.M.(a,b)=a\times b$$
=> $$a\times72=24\times216$$
=> $$a=\frac{24\times216}{72}$$
=> $$a=24\times3=72$$
=> Ans - (B)
