Math Trivia : Find numbers

A～I expresses the number of either 1-9. The result of calculation shows as above. Find each number.

A=9,B=2,C=3,D=4,E=1,F=6,G=8,H=5,I=7

According to A × C = B7, 2 is applied to B .

According to A×E×I＝F3, 6 is applied to F.

According to the result of this calculation, A=9 and E×I＝7. D×E×F＝D×E×6＝24，D×E ＝4．

Because E is a common divisor of 7 and 4, E=1.
