What are the boundary conditions ? Is that a cantilever beam or are the supports different ? You could use analytical equations from the literature or run a simple FEA.

You can find a few formulas for natural frequencies in Roark's Formulas for Stress and Strain. For more, check "Formulas for Natural Frequency and Mode Shape" by R.D. Blevins.
