how convert very high frequency like 10Mhz to say 10Khz for an ac no change in any other parameters
easiest and cheapest...all methods
also is it possible just to use a LPF.
i want to convert a signal from crystal oscillator to low frequency say 10Khz frequency
 

A filter isn't going to work.

What do you actually mean by "convert"? If you have a square-wave you can use a digital divider. Could you explain more what you are trying to do?
 

If it's for low power digital signal than you can use a 10-bit digital counter with the divider ratio set to 1000.

A LPF will just reduce the amplitude, not the frequency.

If the signal shape is not very critical ( e.g. out of sinusoid ) use a simple chain of divider by using D-Type latches.Dividers generally work as divide-by-two but other compositions are possible.
 

You can use a counter, specifically - programmable divide by n counter. Something like HEF4059B.
Or you can also use counters like - 74HC393
 

you can use two chips 74HC390 that have 2 decade counters in each . from the chips use three decade counters in series leave the forth one .
if needed have a 74hc or 74ls buffer at the output or even a simple emitter follower would do, i suppose.
