Factors and Multiples
square number
A number that is a result of the product of a number multiplied by itself
Venn Diagram
A diagram in which overlapping circles are used to show relationships among sets of objects that have certain attributes
common factor
A factor that two or more numbers share
even number
A multiple of 2. a number that ends in 0,2,4,6,8.
common multiple
A multiple that two or more numbers share
divisor
A number that divides a given number leaving a zero remainder
prime factorization
A product of numbers, perhaps with some repetitions, resulting in the desired number A number can have many factorizations. Example 3X20 and 2X2X15 are two different factorizations of 60.
prime factorization
A product of prime numbers, perhaps with some repetitions, resulting in the desired number
odd number
A whole number that is not a multiple of 2
proper factor
All the factors of a number, except the number itself. The proper factors of 16 are 1,2,4,and 8.
factor
One of two or more whole numbers that are multiplied to get a product. Example 5X6 = 30. 5 and 6 are both factors of 30.
GCF
The greatest common factor that two or more numbers share. Example : 1,2,3 and 6 are common factors of 12 and 30, but 6 is the greatest common factor.
LCM
The least multiple that two or more numbers share
factor pair
Two whole numbers that are multiplied to get a product. Example 5,6 are a factor pair of 30 because 5X 6=30.
composite number
a number exactly divisible by at least one whole number other than 1 and itself; a number with more than two factors
prime number
a number with only two factors, a number whose only factors are 1 and itself, Remember 1 is not a prime number since it only has one factor!
multiple
the product (result) of multiplying two whole numbers Example: multiples of 3 are 3,6,9,12
product
the result or answer obtained by multiplying two numbers
exponent
the small raised number that tells you how many times a factor is used
