First, I claim that if . Since , then we have
Second, I show that is the smallest integer which satisfies . Suppose the smallest is some , such that . Then we know , for any . So we have , (mod ). is the smallest one, then we must have . This implies that for some . Since , then (mod ). Since ...
There are a variety of proofs in this solution regarding modular arithmetic.
