2 FACTOR A whole number that divides another whole number with a remainder of 0. EXAMPLE Find the factors of 30.

3 MULTIPLE The product of that number and any nonzero whole number.
example Find the multiples of 5. Find the multiples of 8.

4 GREATEST COMMON FACTOR (GCF)
The greatest number that is a factor of all the numbers.

5 Find the LCM of each pair of numbers.
LEAST COMMON MULTIPLE The least multiple that is common to all of the numbers. example Find the LCM of each pair of numbers. 4, 10 12, 15

6 Find the GCF and LCM of 42 and 36.
