We know that, LCM X HCF = product of the numbers
Let the numbers are 'a' and 'b'.
So, a X b = 192 X 16
So, ab = 3072........(I)
Given, a + b = 112
From equation (I) ,
Or, 'a' = (3072/b)
So, (3072/b) + b = 112
So, 3072 + b 2 = 112b
Or, b 2 - 112b + 3072 = 0
Or, b 2 - 64b - 48b + 3072 = 0
So, 'b' = 48 or 64
When, 'b' = 48
So, 'a' = (3072/48) = 64
When, 'b' = 64
So, 'a' = (3072/64) = 48
Therefore, required difference = 64 - 48 = 16
