1) I mean what is that we have to find (The number of ways or the numbers themselves or the least number)
From what I understood it should be
1, 1, 1, 3
rearrange
to get 3, 1, 1, 1
last digit is odd. The last 3 are divisible by the number preceeding them!
but i am not sure if this is what the question asked for!
