only even number is divisible by 6, so 231 is out.
Number must be divisible by 3
3 + 2 + 2 = 7, so that is out
4 + 5 + 4 = 13, that is also out
4+ 3 + 2 = 9 which is divisible by 3
so 432 is divisible by 6 432 / 6 = 72

Well, an easy way would be to type each one into a calculator to see if it is divisible by 6.
A simple way is ...
First, notice that numbers divisible by 6 must be even. That rules out 231.
Second, if a number is divisible by 6 then it must be divisible by 3. And every number divisible by 3 - just add the digits to see if that sum is divisible by 3. So for 322; 3+2+2 = 7 ... not divisible by 3. For 4+3+2 = 9 ... is divisible by 3. For 4+5+4 = 13 ... not divisible by 3.
Thus 432 is the answer. And if you check 432/6 = 72.

numbers that are divisible by 6 is a number divisible by both 2 and 3.
a number is divisible by 2 if it is even.
a number is divisible by3 if the sum of the digits equal a number divisible by 3.
the 2nd, 3rd, and 4th choices are all even.
3+2+2=7 not divis by 3
4+3+2=9 divisible by 3
4+5+4=13 not divis. by 3
the answer is 432
