Select Try the example in the form to load these values and calculate them again. This replaces the current form inputs. Compare the result with the method and worked explanation below.
The method, explained
Repeatedly divide by each candidate factor beginning at 2. After removing a factor completely, continue until the candidate squared exceeds the remaining value. Any remainder above 1 is prime.
360 = 2³ × 3² × 5. Multiplying those factors gives 360.
What to keep in mind
Accepts whole numbers from 2 through one trillion. Zero, one, negative numbers and fractions are outside the supported domain.
Common questions
What happens when the number is prime?
The output is the original number because it has no smaller prime factors.
Is 1 a prime number?
No. Prime numbers have exactly two positive divisors; 1 has only one.
