Summing or Multiplying (Posted on 2006-08-21)

123 is a peculiar integer, because 1+2+3=1*2*3. 1412 is also peculiar, since 1+4+1+2=1*4*1*2.

A simple question: are there infinitely many such numbers?

A not so simple question: if so, are there such numbers for ANY number of digits?

| Comment 11 of 21 |

Now that you found that there are no 24 digit peculiar numbers, what are the next also impossible lengths?
