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.
