The Greatest Common Divisor for two numbers is 8 while their Least Common Multiple is 144. Find the other number if one number is 16. 

  • A.108
  • B.96
  • C.72
  • D.36

Answer: C

For any two numbers,

\[ \text{H.C.F.} \times \text{L.C.M.} = \text{product of the numbers} \]

\[ 8 \times 144 = 16 \times n \quad\Longrightarrow\quad n = \frac{1152}{16} = 72 \]
