1. Prime Factorization
Course 2 3-4

2. Least Common Multiple (LCM)
Multiple of a number is the product of that number and a non-zero whole number
Least Common Multiple (LCM) of 2 or more numbers is the least multiple that is common to all of the numbers

3. Factors
Factor is a whole number that divides another whole number with remainder of 0. Any number is always divisible by all of its factors
Composite Number is a whole number > 1 that has more than 2 factors
Prime Number is a whole number with exactly 2 factors, 1 and the number itself

4. Greatest Common Factor (GCF)
Prime Factorization is writing a number as the product of its prime factors. Can use a factor tree to find the prime factors.
Greatest Common Factor (GCF) of 2 or more numbers is the greatest number that is a factor of all the numbers.
