I don't think it is always divisible by 12 . example number 18 is divisible by 2 and 6 but can't divisible by 12
The postulate which is illustrated for the real numbers 6*12 =12*6 is The commutative property of multiplication. This commutative property of multiplication states that whenever we multiply two numbers,we can multiply then in any other. So if we have two numbers a and b,then we can multiply them as a*b or we can multiply them as b*a. We get the same result.
