What is Factoring in Math?
Factoring breaks down a number into smaller numbers that multiply together to give the original value.
Prime factorization is unique for every positive integer by the Fundamental Theorem of Arithmetic.
Formula & Step-by-Step Calculation
n = p₁^a₁ × p₂^a₂ × ... × pₖ^aₖ
Canonical prime factorization where pᵢ are prime factors.
Worked Step-by-Step Examples
Example 1
Factor 60
Solution: 2² × 3 × 5
• 60 = 2 × 30 = 2 × 2 × 15 = 2² × 3 × 5
