If you multiply 15,873 by any single-digit number, then multiply that by 7, all the answer's numerals will be the first single number you multiplied it with.

If you multiply 37,037 by any single-digit number, then multiply that by 3, every number in the answer will be the same as that first single number.

(Multiplying 37,037 by any single-digit number yields some interesting number patterns.)

Consider the number 512........ 5 + 1 + 2 =8..........8 X 8 X 8 = 512
