comment Is there any way to find sum of sequence generated by formula?
So, there is no formula, where I can put $n$ and get such sum without those loops to calculate $n^2$

Can you give me more details?

This formula gives n-th term and I need a sum of first n terms.

@Tad Also about So lcm(K,N,M) must divide D, if K=2,N=4,M=7,D=3 then lcm=28 and it won't divide D, but lcm is correct answer right now.

@Tad I think you have problem in formula, it should be S = D/(1-1/K-1/N-1/M), but I don't know markup language to edit it properly.

comment How to find connection between sequence and formula?
Yes. I started with finding formula for this sequence. But found it only on OEIS. I can try to write some loops which will generate those numbers. But as I can see formula is the best solution in this case.

If you need to implement computer algorithm for it, how would you start?
