Answer Posted / truong nguyen

1. A*B*C=B*G*E=D*E*F => B*G=D*F and A*C=G*E (1.a).
2. From numbers in 0,..9, we found these equalities:
9*2 = 6*3
8*3 = 6*4
8*1 = 4*2
6*2 = 4*3
3. In these equalities, only (9*2 = 6*3 and 8*1 = 4*2)
satisfies (1.a) that only one number (number 2) exists on
both two equalities.
4. G = 2.
