Hello, it is really  SIMPLE  statement,  and you do not need to use heavy artillery as that referred theorem.



This statement is for those  BEGINNERS  who solve their first problems on divisibility numbers

and make their first steps in learning this subject.



Trace attentively my reasons below.



<pre>
    Of any three consecutive integer numbers, at least one is an EVEN number (divisible by 2)
    and exactly one is divisible by 3.


    These are self-evident facts.


    Hence, the product of any three consecutive integer numbers is divisible by 2*3 = 6.

Solved, proved, explained and completed.
