MetaNumbers - Number Encyclopedia

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).

How to use MetaNumbers ?

Just type a number value (for example 3600) in the search field (it can be in decimal, factorized, binary, or hexadecimal form) and you'll be able to:

• Check whether 3600 is a prime number.

• Compute the prime factors of 3600 (2^4 × 3^2 × 5^2) and all its positive divisors (45).

• 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 number classes 3600 belongs to (among more than 70, such as the square, the perfect power, or the abundant numbers).
