1. Factor­ a whole number that divides evenly into another whole number
a whole number that can be multiplied by another whole number to result in a given product
Prime Number­ has only 2 factors, 1 and itself ex. 17 ­ 1,17
Composite Number­ has 3 or more factors ex. 12­ 1,2,3,4,6,12
2. Product­ the result of multiplication
Odd Number­ Any whole number that does not have 2 as a factor
­will have 1, 3, 5, 7 or 9 in ones' place
Even Number­ any whole number that is divisible by 2
­any whole number that has 2 as a factor
­will have 0, 2, 4, 6 or 8 in ones' place
Multiple the product of a whole number and any other whole number
Ex. The multiples of 6­6, 12, 18, 24, 30, 36, 42, 48, 54, 60...
Greatest Common Factor (GCF) the largest factor that 2 or more numbers have in common
ex. To find the GCF of 20 and 36 1. list the factors of each number
2. Circle or underline the common factors
3. the GCF is the common factor with the greatest value
20­1, 2, 4, 5, 10, 20
36­ 1, 2, 3, 4, 6, 9, 12, 18, 36
GCF= 4
Least Common Multiple (LCM) the smallest multiple that 2 or more numbers have in common
ex. To find the LCM of 6 and 8
1. list the 1st ten multiples of the each number
2. cirlcle or underline all of the common multiples
3. the LCM is the common multiple with the least value
6­ 6, 12, 18, 24, 30, 36, 42, 48, 54, 60...
8­ 8, 16, 24, 32, 40, 48, 56, 64, 72, 80... LCM=24
