Study Notes
- Prime factorization is the process of finding the unique prime numbers that can be multiplied together to get a composite number.
- Prime factors are special because they can only be divided by 1 and themselves.
- To find prime factors, multiply together the identified prime numbers until the result matches the original number.
- The prime numbers under 30 are commonly used in prime factorization.
- Serial factorization method involves factoring out the smallest prime number repeatedly until the remaining factors are prime.
- Prime factors can be organized in a table (tee chart) for easy reference during serial factorization.
- Factor tree method involves breaking down the number into factors and continuing the process with each resulting factor until prime factors are reached.
- Prime factorization is used for various purposes, including finding greatest common factors (GCF) and least common multiples (LCM).
- Greatest common factors are the largest numbers that can divide two numbers evenly, and can be found by identifying common prime factors.
- Least common multiples are the smallest numbers that two numbers can be multiplied into, and can also be found by identifying common prime factors.
