How to get the Sum of Lowest values in 3 rows each added dynamically – Jquery ajax

$(document).ready(function() {
  var i = 1;
  $("#Add_BDSP").click(function() {
    $('#BDSP' + i).html("<td><input type='text' name='QuotedAmount1[" + i + "]' placeholder='Quoted Amount' class='form-control' /><input type='text' name='QuotedAmount2[" + i + "]'placeholder='Quoted Amount' class='form-control' /><input type='text' name='QuotedAmount3[" + i + "]' placeholder='Quoted Amount' class='form-control'/></td>");

    $('#Tab_BDSP').append('<tr id="BDSP' + (i + 1) + '"></tr>');
    i++;
  });
  $("#Delete_BDSP").click(function() {
    if (i > 1) {
      $("#BDSP" + (i - 1)).html('');
      i--;
    }
  });

});



$(document).on('change', '#Tab_BDSP tbody tr td input[type="text"]', function() {
  let result = 0;
  var MulRes = $('input#ServiceTotalCost');

  var QuotedAmount1 = $(this).parent().find('input[type="text"]').eq(0),
    QuotedAmount2 = $(this).parent().find('input[type="text"]').eq(1),
    QuotedAmount3 = $(this).parent().find('input[type="text"]').eq(2);

  var Qoute1 = (isNaN(parseInt(QuotedAmount1.val()))) ? 0 : parseInt(QuotedAmount1.val()),
    Qoute2 = (isNaN(parseInt(QuotedAmount2.val()))) ? 0 : parseInt(QuotedAmount2.val()),
    Qoute3 = (isNaN(parseInt(QuotedAmount3.val()))) ? 0 : parseInt(QuotedAmount3.val());

  var min = Math.min(Qoute1, Qoute2, Qoute3);
  $(this).parent().attr('data-lowest', min)


  $('#Tab_BDSP tbody tr td').each(function() {
    result += +$(this).attr('data-lowest')
  });

  MulRes.val(result)
});

Thank you for kind response,
the code is running perfect,
but the issue is if i change the value in additional rows,
it adds the lowest into the sum,
e.g. 1st row have 300000 400000 500000 and second row have 600000 700000 800000 The total sum will be 900000 which is perfect. but if i change the value from 600000 to 200000 it should shows 700000 but it gives value of 1100000. Your kind help is needed to rectify this issue in the given code. – ADIL I.T 8 mins ago
