What Is Prime Factorization?

Prime factorization is the process of decomposing a number into its prime factors. Every integer greater than 1 has a unique prime factorization.

How to Use

  1. Start with the smallest prime (2)
  2. Divide repeatedly until a prime no longer divides
  3. Move to the next prime (3, 5, 7, …)
  4. Stop when you reach √n
  5. If the remainder > 1, it is prime

Examples

Example 1: Factorize 84

84 = 2² × 3 × 7

Example 2: Factorize 360

360 = 2³ × 3² × 5

Example 3: Factorize a Prime (97)

97 = 97
