a certain number of times, which can be found using Legendre's Formula. For a prime to survive in the final quotient, it must appear more times in the numerator ( ) than it does combined in the denominator ( Let’s look at primes For any prime in this range, appears exactly once in the numerator ( In the denominator, since appears exactly zero times in Therefore, every prime between 101 and 199 will divide (200100)the 2 by 1 column matrix; 200, 100 end-matrix; exactly once. a3+b3+c3−15=18a cubed plus b cubed plus c cubed
