Which of the following integers is a divisor of(15!+10)? Choose the correct choice.
A) 15	B) 4	C) 3	D) 10	E) 9
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 + 10) = 10 (1*2*3*4*5*..*9*11*12*13*14*15 + 1) We obtain this by taking 10 common.   Hence 10 is definitely a divisor of (15! + 10).   Ans 10
