    Undergrad Number of Integers (<N) divisible only by one power of 2

    Also, I've worked out the problem a bit more: For n < N, n = p1^a1 * p2^a2 * p3^a3. ... and so on where pi are prime factors of n and ai are powers of pi. We know the highest power of a prime factor, pi is ai_max = log(n) - where base of log is pi. I.e. ai_max = int(log(n,pi)) Thus, every...

    Undergrad Number of Integers (<N) divisible only by one power of 2

    Hi, The original problem was : for a given number k = d + n/d, where d is a divisor of another number n, how many k <= N are prime? When I looked at this problem, for k to be prime > 2, it has to be odd. This implies d and n/d can't both be even or odd. If d = 2, then d is even and n/d has...
