Factor any whole number into its prime building blocks, shown both in exponent form and as a full list, with a check for whether the number itself is prime.
How it works
- Type an integer to factorize.
- The engine divides by successive primes mathematically.
- Review the broken-down prime elements in exponent format.
Frequently asked questions
What is prime factorization?
Expressing a number as a product of primes — for example, 360 = 2^3 x 3^2 x 5. Every integer has a unique factorization.
Why does it matter?
It underlies finding GCD and LCM, simplifying fractions, and much of number theory and cryptography.
How big a number can it handle?
Up to about a trillion comfortably. Very large semiprimes (as used in cryptography) are deliberately hard to factor.
