Questions & Answers
Q: What is prime factorization?
Prime factorization is the process of breaking down a number into its prime factors, which are numbers that can only be divided by one and themselves. It involves finding the smallest prime numbers that can multiply to give the original number.
Q: How do you determine if a number is prime or not?
A number is prime if it can only be divided by one and itself. To determine if a number is prime, you can check if it is divisible by any numbers other than one and itself. If it is not divisible by any other numbers, it is prime.
Q: What are factors?
Factors are the numbers that can evenly divide a given number. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12, because these numbers can divide 12 without leaving a remainder.
Q: Can a number have multiple prime factorizations?
No, a number can only have one prime factorization. The prime factorization is unique for each number, and it is obtained by finding the prime numbers that can multiply to give the original number.
