I have updated the code. This is what you are looking for

$('select').change(function() {
  if ($(this).val() == 'other') {
    $('#select1, #select2, #select3').not(this)
      .children('option[value="other"]')
      .remove()
  } else {
    if ($('#select1, #select2, #select3').not(this).find('option[value=other]').length > 0) {

    } else {

      ($('#select1, #select2, #select3').not(this)
        .append('Other'))
    }
  }
});
