Web1. A positive integer n is called highly divisible if d ( n) > d ( m) for all positive integers m < n. My book said that "All but finitely many highly divisible integers a are divisible by 2 and by … WebHighly composite numbers are numbers such that divisor function d(n)=sigma_0(n) (i.e., the number of divisors of n) is greater than for any smaller n. Superabundant numbers are …
Project Euler #12 (Highly divisible triangular numbers) in Python 3.x
WebFeb 15, 2024 · The number of divisors can now be determined. The code to solve Euler Problem 12 is shown below. The loop continues until it finds a triangular number with 500 divisors. The first two lines increment the index and create the next triangular number. The third line in the loop determines the number of times each factor is repeated (the run … WebSubtract the last digit from a number made by the other digits. If that number is divisible by 11 then the original number is, too. Can repeat this if needed, Example: 286 28 − 6 is 22, which is divisible by 11, so 286 is divisible by 11 Example: 14641 1464 − 1 … northern regional college newtownabbey
Project Euler 12 Solution: Highly divisible triangular number
A highly composite number is a positive integer with more divisors than any smaller positive integer has. A related concept is that of a largely composite number, a positive integer which has at least as many divisors as any smaller positive integer. The name can be somewhat misleading, as the first two highly … See more Roughly speaking, for a number to be highly composite it has to have prime factors as small as possible, but not too many of the same. By the fundamental theorem of arithmetic, every positive integer n has a … See more If Q(x) denotes the number of highly composite numbers less than or equal to x, then there are two constants a and b, both greater than 1, such that $${\displaystyle (\log x)^{a}\leq Q(x)\leq (\log x)^{b}\,.}$$ The first part of the … See more • Weisstein, Eric W.
