consider 9 first of all. The sum of all digits must be a number which is divisible by 9.
A: 16 --> out
B: 19 --> out
C: 18 ---> yeah
D: 28 ---> out
E: 22 -----> out

Hey Matt,
Champions know that there is no shortcut..... Just kidding buddy

I got C 46320

the way I did it is that, I calculated the LCM which is 11*12*13*15 = 25740

now I figured because 25* 18 is 450, so the answer choice will be close to that..
so multiplying 25740 by 12 gives me 463320. Bingo that is choice C

took me approximately 3 minutes to do it.

Laxie and Nakib, you guys are Q-Masters!

OA is C

I made the mistake of multiplying all the factors together and the doubled the product. Took over 3 minutes. Laxie`s method takes less than 30 seconds.
