About this app

Prime Factorization Calculator breaks any whole number down into the prime numbers that build it — completely offline. Type a number and instantly see its prime factorization in exponent form, the full expanded product, a visual factor tree, and every divisor it has.

WHAT YOU CAN DO
• Factor any whole number from 2 up to 1,000,000,000,000,000 (10^15)
• Read the result as a clean exponent form, e.g. 360 = 2³ × 3² × 5
• See the expanded product: 2 × 2 × 2 × 3 × 3 × 5
• Watch a factor tree draw the breakdown step by step
• Check whether a number is prime at a glance
• See the distinct prime count, total prime factors, number of divisors and the sum of all divisors
• Browse the complete list of divisors
• Tap built-in examples (360, 1024, 97, 5040) to load them instantly

CLEAR RESULTS
The number 1, zero, negatives and non-integers are met with a friendly explanation instead of a wrong answer or a crash. Primes are clearly flagged, and very large inputs are capped so the app stays fast.

LEARN AS YOU GO
A built-in Learn tab explains, in plain language, what prime factorization is, what makes a number prime, and the fundamental theorem of arithmetic — the rule that every number has exactly one prime fingerprint. Great for students, teachers, and anyone brushing up on number theory.

PRIVACY
The app collects no personal data and works fully offline — the numbers you enter never leave your device. Ads are served by Google AdMob, which may use an advertising identifier as described in Google's policies.

EDUCATIONAL USE
This tool is intended for general and educational use. Results are computed on your device from the value you enter.

Light and dark themes, a tiny download, and no clutter. Download Prime Factorization Calculator and factor with confidence.
