Question 317488
What is the sum of the digits of the smallest positive integer that is divisible by 2, 3, 4, 6, and 7?

A)14 B)16 C)9 D)12 E)15


A number that is divisible by all the above numbers is their multiple, and since we're looking for the smallest multiple, we just need to find the least common multiple, or LCM of the numbers.


The LCM of 2,3,4,6, and 7 is 84, and the sum of the digits of 84 is {{{highlight_green(12)}}} (8 + 4).
