When we say 15!, it just means 1*2*3*4*5*...*13*14*15
So you need to find the integer which is a divisor of
(1*2*3*4*5*...*13*14*15 + 13) = 13 (1*2*3*4*5*...*12*14*15 + 1) We obtain this by taking 13 common.
Hence 13 is definitely a divisor of (15! + 13).

It should be C. 15!+13= 13( 1*2*3*....12*14*15+1)
Therefore 13 is the answer
Therefore 13 is the answer
