The number is 381654729 because

38165472 / 8 = 477068
3816547 / 7 = 545221
381654 / 6 = 63609
38165 / 5 = 7633
3816 / 4 = 954
381 / 3 = 127
38 / 2 = 19
3 / 1 = 3

Answer 2

I am not sure what you are doing but 381654729 is not divisible by 2

1*2*3*4*5*6*7*8*9
take out factors of bigger numbers
5*6*7*8*9
do not need 6 because 2 in 8 and 3 in 9
5*7*8*9
= 2520
