Find a basis for the subspace of R^4 spanned by, S={(6,-3,6,340, (3,-2,3,19), (8,3,-9,6), (-2,0,6,-5)

Figured I would set up the linear combination to test for independence.

Have you done row reducing?

Because that would also be an approach to determining if they are linearly independent.

I made up the columns, solved for rref, and came up with the trivial solution

If the determinant of the matrix these vectors make is 0 then some of them are linearly dependent.
