숫자가 카운팅되는(?) 스크립트 다중이용 코드정리 문의 채택완료

.up_number 안에 .memberCountConTxt1~4 숫자가 카운팅되는 스크립트입니다.

4개 사용할때 이렇게 사용했는데 코드를 조금 축소할 수 있는 방법이 있을까요?

현재 잘 구동되는 스크립트 코드 입니다!

var isVisible = false;

$(window).on("scroll", function () {
  if (checkVisible($(".up_number")) && !isVisible) {
    var memberCountConTxt1 = 22;
    var memberCountConTxt2 = 346;
    var memberCountConTxt3 = 776;
    var memberCountConTxt4 = 126;
  
  $({ val : 0 }).animate({ val : memberCountConTxt1 }, {
   duration: 1500,
  step: function() {
    var num = numberWithCommas(Math.floor(this.val));
    $(".memberCountCon1").text(num);
  },
  complete: function() {
    var num = numberWithCommas(Math.floor(this.val));
    $(".memberCountCon1").text(num);
  }
});

function numberWithCommas(x) {
    return x.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");
    }
      $({ val : 0 }).animate({ val : memberCountConTxt2 }, {
   duration: 1500,
  step: function() {
    var num = numberWithCommas(Math.floor(this.val));
    $(".memberCountCon2").text(num);
  },
  complete: function() {
    var num = numberWithCommas(Math.floor(this.val));
    $(".memberCountCon2").text(num);
  }
});

function numberWithCommas(x) {
    return x.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");
    }
      $({ val : 0 }).animate({ val : memberCountConTxt3 }, {
   duration: 1500,
  step: function() {
