Lead isotopes to tend to correspond to the mass number of the element next to lead in the periodic table.
Lead tends to end most of the decay series of elements. This makes lead isotopes to be very many and its important to discover the most stable of them all.
However, the mass number of most of these isotopes of lead to tend to correspond to the mass number of the element next to lead in the periodic table hence, it becomes difficult to exactly predict the common isotope of lead.
