461.860 isn't a valid frequency (perhaps 461.8625 should be your reference frequency with 12.5khz step side considered). You need to determine LSNs first before you can determine an LCN or run LCN Finder on a Uniden x36HP or SDS
DMR T3 systems are kinda made up by the Installer Administrator. They are not like Motorola Trunking Systems that always follow the same numbers for the same frequencies. You Have to find all frequencies then find 1 or 2 LNC's then use a calculator or a SDSx00 or BCDx36 scanner with LNC Finder to know for sure.

It helps if you have a cheap SDR dongle, a $25-$50 cost and run SDR# and DSDplus or have a discriminator output for DSDplus as it will allow you to monitor the control channel, it is a fixed frequency and slot in DMRIII, and see what LSN it sends for a voice channels TG and you find that voice frequency with that TG either by monitoring or looking at the SDR# spectrum and calculate the frequency for all other LSN that the control channel sends.
There's a LCN calculator here at RR in a post by thewraith2008.
For an unknown DMRIII system it is best to search the whole frequency range, something like 460MHz-465MHz for all constant DMR signalling that will indicate a DMRIII sites control channel to check how many sites you can find and write down site ID and its frequency. Then monitor those control channels using DSDplus for the adjacent site info that will be a LSN channel and site ID and match with the control channels info you have written down. Then you will have both the frequency and LSN for several control channels and use the calculator to get both the LCN for a scanner and the voice frequencies that are in use.

Once you determine the LSNs (or Ch IDs) of one frequency (they'll always be two sequential numbers, one LSN per timeslot) download & run the LCN calculator linked here to enter frequency and one of its LSNs to use as a starting reference, it should then map the remaining LSNs for every frequency in range then give you the corresponding LCNs
I do not now the number do not know what number to had or divide I am just going to give up that anyhow
