    A point to be noted here is that if in final t1 we get negative ans then our final multiplicative answer will be (a+t1)

    take A=modulo part , B=number part , ex: if we have to find MI of 20 mod 9 then take A=9 and B=20 then you will get correct ans.

    Fun fact for this algorithm: the rule "A>B" is not neccesary, because the algorithm takes this into account by the way it behaves. For example if you have 3 mod 5 and take A = 3 and B = 5, then you get remainder 3 and quotient 0, so in the next iteration you would get A = B (which was 5) and B = remainder (which was 3). As you can see the algorithm takes care of that "point to ponder" by itself, you just waste 1 iteration tho

    I’m offering a course in cyber security called cryptography and steganography.
    Your channel has been really helpful!! So thank you!!
    I’m about to write a test and I’m only able to easily find the mod multiplicative inverse with the use of a good scientific calculator that has mod function. In case Calculator won’t be allowed in the test, so I’m looking for easy manual way of finding the inverse.
    But what I see here is scary!!
    In one of my workings i need the inverse of 441 mod 26. Obviously there’s no time for this Method. If Calculator isn’t allowed in the test, I’m screwed!!
    Mod multiplicative inverse is one such thing that shouldn’t be hard, BUT IT IS!!

    The Extended Euclidean Algorithm taught seems incorrect. It gives the M.I. of 35 mod 3 to be 12. However, 35 × 12 = 420 which is divisible by 3, hence not 420 is not congruent to 1 modulo 3, hence 12 is not M.I. of 35 mod 3

    • @moonblade5838
      @moonblade5838 9 месяцев назад

      Method is correct, maybe u got -12 which is 35+12=47 i.e M.I of 35 mod 3

    Stating A should be greater than B is very misleading and flawed. Because, taking your own example 3, the multiplicative inverse of 26 mod 11 is 3, while the multiplicative inverse of 11 mod 26 is 19. But when you say you assign the greater value to A, you're implying they would both be the same. And you can only find the MI of 11 mod 26 using your method, which a flawed and inaccurate method.

    • @gautham4232
      @gautham4232 10 месяцев назад

      91mod12 = 7. If you start with A=12, B=7, T1=0 and T2=1, the multiplicative inverse will come as 7.
