  2. Divisibility rule - Wikipedia

    en.wikipedia.org/wiki/Divisibility_rule

    We also have the rule that 10 x + y is divisible iff x + 4 y is divisible by 13. For example, to test the divisibility of 1761 by 13 we can reduce this to the divisibility of 461 by the first rule. Using the second rule, this reduces to the divisibility of 50, and doing that again yields 5. So, 1761 is not divisible by 13.

  3. 1001 (number) - Wikipedia

    en.wikipedia.org/wiki/1001_(number)

    Two properties of 1001 are the basis of a divisibility test for 7, 11 and 13. The method is along the same lines as the divisibility rule for 11 using the property 10 ≡ -1 (mod 11). The two properties of 1001 are 1001 = 7 × 11 × 13 in prime factors 10 3 ≡ -1 (mod 1001) The method simultaneously tests for divisibility by any of the factors ...

  5. Sanity check - Wikipedia

    en.wikipedia.org/wiki/Sanity_check

    Dimensional analysis may be used as a sanity check of physical equations: the two sides of any equation must be commensurable or have the same dimensions. A person who has calculated the power output of a car to be 700 kJ may have omitted a factor, since the unit joules is a measure of energy, not power (energy per unit time).

  8. Fermat's little theorem - Wikipedia

    en.wikipedia.org/wiki/Fermat's_little_theorem

    The Miller–Rabin test uses this property in the following way: given an odd integer p for which primality has to be tested, write p − 1 = 2 s d with s > 0 and d odd > 0, and choose a random a such that 1 < a < p − 1; then compute b = a d mod p; if b is not 1 nor −1, then square it repeatedly modulo p until you get −1 or have squared s ...
