Combined Divisibility Rule of 7,11,13 and 1001 - Video Lecture


Dear friends In this video lecture I will discuss the combined divisibility rule of 7,11 and 13. Now by saying the combined divisibility rule of 7,11 and 13 & 7,11 and 13 are co-prime with each other so it is equivalent to the divisibility rule of 1001 which is the product of these three co-primes 7,11 and 13. The proving of these divisibility rules method is being showed in this video lecture.

In case you have doubts post them in the comment section below.

  4. Sir Can you please help with this problem
    Let say I have taken a number 713256
    Now I'm checking its remainder when divided by 11
    As you said in order to check its remainder do the following that is
    (-713 + 256 )/ 11 = -457/11 , Now on dividing it I get remainder as 6
    But when I divide the number i.e 713256 I get remainder as 5
    Why so ? Kindly help me out
