Question

Find the greatest number which divides the following completely :-(84,112,280) tell me all the proceedings​

Answer 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.

Answer 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
