Are just the factors that two or more numbers have in common. (These are also called "common divisors.")
Greatest Common Factor (GCF)

Are just the multiples (products) that two or more numbers have in common.
Least Common Multiple
The least common multiple (LCM) of two numbers is the smallest number (not zero) that is amultiple of both.
Fractions are for counting PART of something.
When two values are equal we use the "equals" sign example: 2+2 = 4
When two values are definitely not equal we use the "not equal to" sign example: 2+2 ≠ 9
When one value is smaller than another we use a "less than" sign example: 3 < 5
When one value is bigger than another we use a "greater than" sign example: 9 > 6
