Smallest prime number factor of 15

WebbAssume m is divisible by k, and k is the smallest factor (other than 1). Also assume k is not prime, it must be divisible by some number n, such that n < k But if n divides k, it must also divide m. This contradicts our original statement that k is the smallest factor. Thus k must be prime.
