This means that if you have a gcd function that works for two arguments, you can lift it to a collection using LINQ's Enumerable.Aggregate. That does not involve recursion, and optimizing it (if necessary) is probably as simple as sorting the collection. – cunter savognin

The GCD is an associative function: gcd(a, gcd(b, c)) = gcd(gcd(a, b), c). Thus gcd( a , b , c , ...) can be used to denote the GCD of multiple arguments. The GCD is a multiplicative function in the following sense: if a 1 and a 2 are relatively prime, then gcd( a 1 ⋅ a 2 , b ) = gcd( a 1 , b )⋅gcd( a 2 , b ) . See more In mathematics, the greatest common divisor (GCD) of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers. For two integers x, y, the greatest common divisor of … See more Reducing fractions The greatest common divisor is useful for reducing fractions to the lowest terms.

Because the inner loop increments in steps of d, and stops when it gets back to the starting point, i.e. a total span which is some multiple of n.That multiple is LCM(n, d).Thus the number of elements in that cycle is LCM(n, d) / d.The total number of such cycles is n / … marginalisierte definitionWebAug 30, 2024 · The first thing that should be marked is that GCD(A[i-1 : j]) * d = GCD(A[i : j]) where d is natural number. So for the fixed subarray end, there will be some blocks with equal GCD, and there will be no more than *log n* blocks, since GCD in one block is the divisor of GCD of another block, and, therefore, is at least two times smaller. marginalise definitionWeb$\begingroup$ @usul D.W's link is exactly that problem.
