If A and B are two numbers and L and H  are their lcm and hcf respectively then         A×B=L×H  Here A=30, L=150, H=5        30×B=150×5         B=((150×5)/(30))=25  Other number is 25
$$\mathrm{If}\:\mathrm{A}\:\mathrm{and}\:\mathrm{B}\:\mathrm{are}\:\mathrm{two}\:\mathrm{numbers}\:\mathrm{and}\:\mathrm{L}\:\mathrm{and}\:\mathrm{H} \\ $$$$\mathrm{are}\:\mathrm{their}\:\mathrm{lcm}\:\mathrm{and}\:\mathrm{hcf}\:\mathrm{respectively}\:\mathrm{then} \\ $$$$ \\ $$$$\:\:\:\:\:\mathrm{A}×\mathrm{B}=\mathrm{L}×\mathrm{H} \\ $$$$\mathrm{Here}\:\mathrm{A}=\mathrm{30},\:\mathrm{L}=\mathrm{150},\:\mathrm{H}=\mathrm{5} \\ $$$$\:\:\:\:\:\:\mathrm{30}×\mathrm{B}=\mathrm{150}×\mathrm{5} \\ $$$$\:\:\:\:\:\:\:\mathrm{B}=\frac{\mathrm{150}×\mathrm{5}}{\mathrm{30}}=\mathrm{25} \\ $$$$\mathrm{Other}\:\mathrm{number}\:\mathrm{is}\:\mathrm{25} \\ $$

Sir prakash jain, Feels the forum strange  without you, Yozzii, filup and 123456−I mean   active participation.(Although at the moment   also, forum is not empty from experts!)
