b)2(15!)(16!)(17!)
Take 15! common from 1st row,16! common from 2nd row and 17! common from 3rd row and then proceed..

But anurag, if we take 15!, 16! and 17! common, then after doing row and column operations, isnt the determinant coming to be zero ?

Dwijaraj Paul Chowdhury No...I guess after taking 15! in common you got 1, 16 and 17 in the row/column...i made a similar mistake first..it should be 17*16 ,16 and 1 and same for all other cases as well
