Let L(387) be the least residual set modulo 387. If we multiply L(378) by 12, is the resulting set a complete residual set?
Explain your answer please.
I know the answer is yes, but have no idea why?

129 * 12 = 4 * 387
So a counterexample is the best to show that if another integer exist in L(387), then its not a complete residual set?
Is that what it means? If i got it all wrong can you explain to what the question is asking?
