171 / <unknown> = <some number> remainder 7 First, 171-7=164 Purpose: all factors of 164 would be either <unknown> or <some number> 164= 1 x 164 2 x 83 Factors of 164: 1, 2, 83, 164 Since you wanted two digit numbers, the only answer is 83. Proof: 171 / 83 = 2 R 7 * * * * * The last time I checked, 2*83 was not 164, but 2 times 82 was. So, the correct answers are 82 and 41.
