B = A x B --> 0 = 4 x 0
C = C x AB --> 1 = 1 x 40
D = A + AB --> 5 = 4 + 40
AB = 2(CD + Z) where z is the 2nd smallest common divisor
Second smallest common divisor = 5
40 = 2(15 + 5)

002: 6027
B = A x B --> 0 = 6 x 0
C = C x AB --> 2 = 2 x 60
D = A + AB --> 7 = 6 + 60
AB = 2(CD + Z) where z is the 2nd smallest common divisor
Second smallest common divisor = 3
60 = 2(27 + 3)
