  We can obtain a condition on y as follows. Suppose z 1y = z 2y (mod n). Then by definition, this means for some k we have y(z 1 z 2)=kn. Let d be the greatest common divisor of n and y. Then n=d divides z 1 z 2 since it cannot divide y, thus we have z 1y =z 2y (mod n) if and only if z 1 =z 2 (mod n=d):

  not a multiple of 11. Compute Y. Solution 1. Consider the ordered pairs of digits (X;Y) for which 123X5Y7 is a multiple of 11. Recall that a number is a multiple of 11 if and only if the alternating sum of the digits is a multiple of 11. Because 1+3+5+7 = 16, the sum of the remaining digits, namely 2+ X+Y, must equal 5 or 16.
