What's the test like?

Very stupid algo that in a single loop from i=2 to 2*10^6 checks whether i|N works
Because of if we take any combination Factor[20] of primes where at least one Factor[j]>2*10^6 than product of Factor[j] larger than 10^18.

Try tests like 2^18 multiplied with twin primes, all should yield yes.

All yes.

The thing is you should go up to sqrt(n/(2^18)) not sqrt(n/(2^19)).

Dear Ciprian, I think that some of your samples are wrong. 3145728=2^20*3^1 and the answer should be No. The same situation is for the last number, 203696898048 (my accepted program outputs No).

Marginean Ciprian, I think you are wrong, I got this.
