Exponential Form (Prime Factorization) Calculator
The Exponential Form Calculator writes a whole number as a product of prime powers, such as 72 = 2³ × 3². Enter a whole number greater than 1.
Formula
Factor into primes, then group repeated primes as powers
- Every integer greater than 1 has a unique prime factorization.
- Repeated prime factors are written as a power, e.g. 2 × 2 × 2 = 2³.
72
Inputs
- Number: 72
72 = 2 × 2 × 2 × 3 × 3 = 2³ × 3².
