math.number-theory-primes Calculator
Lists primes up to a limit, checks Goldbach's conjecture for even numbers, and computes the prime counting function π(n). The Prime Number Theorem states π(n) ≈ n/ln(n) — the density of primes thins out but never drops to zero.
Inputs
N
Count of items or occurrences.
P
Reference formula or conversion factor shown for context.
Q
Reference formula or conversion factor shown for context.
A
Reference formula or conversion factor shown for context.
Results
GCD(a,n)
GCD (greatest common divisor) -- the largest integer that divides both numbers with no remainder. Used in fraction simplification and modular arithmetic.
phi(p)
pH of the solution. Below 7: acidic. 7: neutral. Above 7: basic (alkaline).
phi(p*q)
pH of the solution. Below 7: acidic. 7: neutral. Above 7: basic (alkaline).
divisors of n
Sample size or count used in the calculation.
n is prime?
Sample size or count used in the calculation.
p*q
Reference formula or conversion factor shown for context.
