What is MetaNumbers.com ?

MetaNumbers is a free math tool providing information about any positive 
integer (up to 9223372036854775807), such as its factorized form, its 
divisors, its classification, or its arithmetic properties (widely used 
in the field of number theory).

Type a number value (n) in the search field (whether in decimal, 
factorized, binary, or hexadecimal form) and MetaNumbers will:

     check whether n is prime or not.
     compute the prime factors of n and all its positive divisors.
     compute various arithmetic functions such as the prime omega 
functions ω(n) and Ω(n), the divisor function τ(n), the sum of divisors 
function σ(n), the Euler's totient function φ(n), the Möbius function 
μ(n), the Liouville function λ(n), the prime counting function π(n), or 
the von Mangoldt function Λ(n).
     check which classes a number belongs to (among more than 70, such 
as the square, the perfect, or the Fibonacci numbers).
     convert n to binary, octal, hexadecimal, etc.
