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. Share Cite Follow answered Mar 12, 2014 at 11:20 Guy WebbGiven a number N, find least prime factors for all numbers from 1 to N.
