Laravel How to DRY Up This Code?

I have the following code in multiple files. I would like to DRY it up.

The purpose of the code is to return the value of the current week which can be 1 to 17.

model Schedule.php

public function scopeCurrentWeekGames($query) {

    return $query->where('week', '=', $this->currentWeek());
}

public function currentWeek()
{
    $currentWeek = Schedule::distinct()
                        ->where('gameTime', '<', Carbon::now()->addHours(50))
                        ->orderBy('gameTime', 'desc')
                        ->lists('week')
                        ->first();

    return $currentWeek;
}

model Pick.php

public function scopeCurrentWeekPicks($query) {

    $currentWeek = Schedule::distinct()
                        ->where('gameTime', '<', Carbon::now()->addHours(50))
                        ->orderBy('gameTime', 'desc')
                        ->lists('week')
                        ->first();

    return $query->where('week', '=', $currentWeek);
}

controller PicksController.php

    $currentWeek = Schedule::distinct()
                        ->where('gameTime', '<', Carbon::now()->addHours(50))
                        ->orderBy('gameTime', 'desc')
                        ->lists('week')
                        ->first();
