a(1) is 15628 = 4 * 3907, using all 10 digits.

(PARI) isok(n) = {fordiv(n, d, q = n/d; sn = vecsort(digits(n), , 8); sd = vecsort(digits(d), , 8); sq = vecsort(digits(q), , 8); sa = vecsort(concat(sn, concat(sd, sq)), , 8); if ((#sa == 10) && (#sn + #sd + #sq == 10), return (1)); ); return (0); } \\ Michel Marcus, Feb 07 2015
