Frequently Asked Questions
What is prime factorization?
Prime factorization is the process of breaking a number down into a product of prime numbers. For example, 60 = 2 × 2 × 3 × 5 = 2² × 3 × 5. Every composite number has a unique prime factorization.
What is a prime number?
A prime number is a whole number greater than 1 that has exactly two factors: 1 and itself. Examples: 2, 3, 5, 7, 11, 13. The number 2 is the only even prime number.
What is a factor tree?
A factor tree is a diagram where you break a number into two factors, then break those factors further until all remaining factors are prime. It is a visual way to find the prime factorization.
Why is prime factorization useful?
Prime factorization helps find GCF and LCM, simplify fractions, and understand number theory. It is also the basis for modern cryptography and computer security.
