%N Values n, where n = p * q, and n, p, and q together contain all 10 digits at least once, and no digit is in more than one of n, p or q.
%e a(1) is 15628 = 4 * 3907, using all 10 digits.
%e 20748 = 13 * 1596, using all 10 digits, but is NOT a member of this sequence, because the digit 1 appears in both p and q.
