1+5+2+8=16 4!=24>>>no of nos that can be formed

24/4=6

6*16=96

96 * 96(10)*96(100)*96(1000)=106656

possible four digit combinations = 4! = 24
sum of digit = 1+5+2+8 = 16
sum of all possible such no = 16*24= 384

1*6+5*6+2*6+8*6=96

96+96(10)+96(100)+96(1000)=106656

Using 1 5 2 8 all possible numbers will be 4!=4*3*2*1=24
And sum of 1+5+2+8=16
so that total sum will be 24*16=384.....

1,5,2,8

4*(4!)=4*(1*2*3*4)

=96

therefore 1000*96 + 100*96 + 10*96 +96 = 106656

96+96(10)+96(100)+96(1000)

Why we have to multiply the digits with 6?
