There are two number A and B. A is a 2-digit number which is a multiple of 8. B is a 2-digit number which is a multiple of 24. What is the largest possible difference between the two numbers A and B?

Smallest multiple of 8: 16

Largest multiple of 24: 96

96 - 16 = 80

(Didn't read the question before this edit, just realized it has to be 2 digit numbers)

A = 16

B = 96
