How would I return the players name with the highest Value?

local function FindTarget()
    for i, v in pairs(otherPlayers)
    do
        if v.Team ~= player.Team then
        local otherTool = v.character:FindFirstCHildWhichIsA("BackpackItem")
            if otherTool.Name == "PlasmaSaber" then
                if otherTool == true then
                    local magnitudes = (v.Positon - player.Position).magnitude < 30 then
                        for i, v in pairs(magnitudes) do
                        local lowest = 0
                            if v <= lowest then 
                                lowest = v

I haven't added any of my 'ends' yet, however I want to return the player with the lowest value to where I called it, any guidance on how I would do this? Also if there's a more efficient way to do what I'm attempting how would I optimize it?
