Powering up the digits IV (Posted on 2011-04-21) Difficulty: 3 of 5
Each of X1, X2 and X3 represents a nonzero digit of the 3-digit base M positive integer X1X2X3; where X1, X2 and X3 are not necessarily distinct.

Determine the possible positive integer values of M, with 7 ≤ M ≤ 206, such that this equation has at least one valid solution.

X1X2 + X2X3 + X3X1 = X1X2X3 ± 6

Note: X1X2X3 denotes the concatenation of the three digits.
