Prime factorization calculator
Factor bounded integers and show prime powers.
Jak používat Prime factorization calculator
The Prime factorization calculator takes a whole number from 2 to 1,000,000,000,000 and returns its prime factors in a table with each prime and its exponent. For example, 360 is listed as 2 to the power 3, 3 to the power 2 and 5. Factors are found by trial division up to the square root of the remaining number.

Časté dotazy
What is the prime factorization of 360?
360 = 2³ × 3² × 5. The calculator lists this as three rows: prime 2 with exponent 3, prime 3 with exponent 2 and prime 5 with exponent 1. 360 is also the default example value.
How can I tell if a number is prime?
Enter it in the calculator. If the result has a single row showing the number itself with exponent 1, the number is prime. Any other result lists its smaller prime factors.
What is the largest number I can factor?
Inputs from 2 up to 1,000,000,000,000 (one trillion) are accepted. The calculator divides by 2 and then by odd numbers up to the square root of whatever remains, and any remainder above 1 is listed as a final prime.
