Flow
  • Enter a positive integer.
  • Review the prime powers shown in multiplication form.
  • Use the factors to support downstream algebra or arithmetic steps.
Example

Worked example: factorizing 360

  1. 1 360 ÷ 2 = 180, ÷ 2 = 90, ÷ 2 = 45
  2. 2 45 = 3 × 3 × 5
  3. 3 Prime factorization = 2^3 × 3^2 × 5

360 factors to 2^3 × 3^2 × 5.

How
  1. Enter a positive integer.
  2. Review the prime powers shown in multiplication form.
  3. Use the factors to support downstream algebra or arithmetic steps.
Avoid
  • Entering decimals instead of integers.
  • Assuming 1 is a prime number.
  • Stopping factorization before all terms are prime.
Checks

Best fit

Prime Factorization Calculator is built for factor integers into prime powers for divisibility, lcm/gcf, and algebra prep. If Prime Factorization Calculator does not match the input scope, compare the answer with a second method.

Input check

Match the entered values to this rule before copying the answer: n = p1^a1 × p2^a2 × ... × pk^ak.

Sanity check

For Prime Factorization Calculator, use the worked example as a quick benchmark: 360 factors to 2^3 × 3^2 × 5. If the prime factorization calculator answer is far away, check whether an input, unit, or mode changed.

Before copying

Review this common issue first: entering decimals instead of integers.

FAQ
