Which of the following numbers is divisible by 6? 

a. 232 

b. 341 

c. 546 

d. 903

Answer: c. 546 

In order for a number to be divisible by 6, it must be able to be divided by six without a remainder. A shortcut to check divisibility by 6 is to see if the number is divisible by both 2 and 3. Since the 546 is even (ends in 6), the number is divisible by 2. Since the sum of the digits is 5 + 4 + 6 = 15 and 15 is divisible by 3, 546 is also divisible by 3. Since 546 is divisible by both 2 and 3, it is also divisible by 6.
