How to check multiple values in an equation in MATLAB?

To size a sedimentation basin for a water treatment process, the length:width ratio must be chosen based off of the given area and should be greater than 5:1. If A = 1390m^2 and the width values are considered in increments of 6m (6, 12, 18,...), how could you iterate through the equation L=A/w in MATLAB with every w value such that L is returned as the smallest calculated value greater than 5?

L=1390./(6:6:1390);
Lmin=L(find(L>5,1,'last'))

Lmin = 5.0362
