You have two options. One is to use a PLL with a VCO at the final frequency and a divide by five counter in the feedback loop to the phase detector.
Ther other method is to use a nonlinear circuit to produce harmonics and then a band pass filter to get the one you want. For these higher harmonics, a step recovery diode is usually used.
The first option is usually the cleanest as far as spurious outputs. The second is the cheapest in some cases if you can tolerate the lower power and spurious signals.
