The HCF and LCM of two numbers are 12 and 924 respectively. Then the number of such pairs is

• The possible number of pairs can be obtained by counting the distinct prime factors obtained from calculating LCM/HCF.
  
  So, in our case,
  
  LCM/HCF = 924/12 = 77
  Prime factors of 77 = 11 x 7
  
  Since there are two prime factors (11 and 7), therefore there will be two such pairs.
  
  First Pair : (12 * 11, 12 * 7) = (132, 84)
  Second pair : (12, 924)
