1. Answer:

   28

   Step-by-step explanation:

   The required greatest number = HCF {(280-84),(112-84),(280-112)}

   So, HCF (196,28,168) =28

   Hence, the greatest number which divides 84,112,280 is 28.

2. Step-by-step explanation:

   take out the HCF of 84,122,280

   2 84. 2 122. 2. 280

   2 56. 2 61. 2. 140

   2 28. 61 1. 2. 70

   2 14 2 35

   7 7. 5. 7

   1 7 1

   84= 2*2*2*2*7

   122=2*2*6

   280= 2*2*2*2*5*7

   H.C.F = 2*2 = 4
