let a divide them to leave 2 as remainder in each case, then:
a divides (137-2), (182-2), (422-2), i.e.,
a divides 135, 180 and 420.
So, a = HCF (135, 180, 420).

Hey friend, Harish here.
Here is your answer:
Let the greatest number that divides them be x.
So, When we subtract the remainder from the number then, x must divide them perfectly.
So, 137 - 2 = 135 , 182 - 2 = 180 , 422 -2 = 420.As x divides the 135, 180, 420,
Then it must be the HCF of them,
Then,
420 = 180 × 2 + 60
180 = 60 × 3 + 0.
130 = 60 × 2 + 10
60 = 10 × 6 + 0.
10 is the HCF Of them.
Therefore 10 is the greatest number that divides them to leave remainder 2.
