What numbers do the letters in the following vertical form represent? A B C D E F * 3 ____________________________ B C D E F A A B C D E F * 3 ____________________________ B C D E F A

What numbers do the letters in the following vertical form represent? A B C D E F * 3 ____________________________ B C D E F A A B C D E F * 3 ____________________________ B C D E F A


Let a be x, B C D E F be y
Then 3 (1000000x + y) = 10Y + X
299999x=7y
y=42857x
X is a one digit integer and Y is a five digit integer
When x = 1, y = 42857
When x = 2, y = 85714
So, two solutions
ABCDEF corresponds to 142857 or 285714, respectively
