Let us say it is...

ABC x DE = FGHI

F can be 1 through 7 (Cannot be 9 or 8 - why?)

E or C cannot be 1 (why?)

Please show us some examples/thoughts that you have tried

There are 7 solutions!

1?? * ??? = ???? (5 start with 1)
The other 2 start with 2 and 4.

Thank you so much for all the help! I did figure out that certain numbers could not be 5, etc. And I realized that there was a high likelihood that the first numbers was 1, so I just kept trying different combinations for a couple of hours. Finally, I found one that worked! Whew! )

Thank you for the suggestions and the help! Glad to know you're here!

Ha! Why couldn't you have listed those when I needed them last night!!!! )

My answer was...... 159 x 48 = 7632

The teacher said there were over 30 possibilities? Can that be right?????

ONLY the 7 I listed ; ask your teacher for one that's different...
