Formulas & Principles
Factor Definition: An integer d is a factor of n if n % d === 0
Prime Factorization: n = p₁^a₁ × p₂^a₂ × ... × p_k^a_k
Prime Number Check: A number > 1 is prime if its only factors are 1 and itself.
Frequently Asked Questions
What is prime factorization?
Prime factorization is the unique decomposition of a composite number into a product of prime numbers (e.g. 48 = 2⁴ × 3).
How do you determine if a number is prime?
A number is prime if it has exactly two distinct positive divisors: 1 and the number itself. If it has three or more factors, it is composite.
What is the difference between factors and multiples?
Factors are numbers you multiply together to reach a target integer. Multiples are what you get when you multiply that integer by another whole number.
