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

If A and B are two numbers,

A X B = HCF of A and B X LCM of Amand B

Therefore, 16 X ? = 8 X 144

Therefore, ? = 72
