--description--

For every integer n>1, the family of functions fn,a,b is defined

by fn,a,b(x)≡ax+b mod n for a,b,x integer and 0

F(N)=∑R(n4+4) for 1≤n≤N. F(1024)=77532377300600.

Find F(107) (mod 1 000 000 007)

--hints--

euler446() should return 907803852.

assert.strictEqual(euler446(), 907803852);

function euler446() {

  return true;
}

euler446();
