i am a 4 digit number. the sum of my digit is same as the product of my digits, who am i?

Answer 1

abcd = a+b+c+d

I made a chart showing colums for
a, b, c, and d
playing around with some numbers, I found
1124 to work
Of course any permutation of 1124 would also work,
e.g. 4121

See if you can some more.
