This is a video of problem about Mathematics Out Standing Student which is related to divisible and divisor. In order to solve this type of problem, you need to use formula of a^n - b^n to make factor of prime. Such as fact, 2010=67.30 then I will show that the following number is both divided by 30 and 67. I know that, GCD(30;67)=1 then If that number divided to 2010, then It will also divided by 30 and 67.
In this video, I show clearly both 30 and 67 when I just use the one formula.
