Factor A number that divides exaclty into another number. Ex 1,2,3, and 6 are factors of 6.  
Prime Number  A whole number with exaclty two factors, itself and 1. Ex. 2,3,5,7,11 are prime numbers. Note: 1 is not a prime or composite number since it only has 1 factor.  
Composite Number  A number with 3 or more factors. Ex 8 is a composite number because its factors are 1,2,4,8. 
Deficient Number A composite number whose factors (excluding itself) do not add up to the number. Ex the factors of 8 are 1,2,4 and 8. 1+2+4=7, therefore, 8 is a deficient number. 
Abundent Number A composite number whose factors (excluding itself) add up to more that the number itself. Ex the factors of 12 are 1,2,3,4,6 and 12. 1+2+3+4+6 = 15, therefore 15 is an abundant number.  
Perfect Number A composite number whose factors (excluding itself) add up to exactly the number itself. Ex the factors of 6 are 1,2,3 and 6. 1+2+3 = 6, therefore, 6 is a perfect number.  
Common Factor  A number that is a factor for two (or more) numbers. Ex 3 is a common factor for 9, 15, 21. 
GCF  Greatest Common Factor is the largest common number that divides into each number is a set. Ex 1 and 5 are common factors of 10 and 15, but 5 is the greatest common factor.  
Multiple  When a number is multiplied by 1,2,3,4,5..., or by skip counting. Ex multiples of 8 are 8,16,24,32,40...  
Common Multiple  When multiples are the same for two numbers. Ex Multiples of 6 are 6, 12, 18, 24, 30... Multiples of 4 are 4, 8, 12, 16, 20, 24, 28... The common multiples of 4 and 6 are 12, 24, 36...  
LCM  Lowest Common Multiple. The lowest multiple that is the same for two (or more) numbers. Ex Common Multiples for 4 and 6 are 12, 24, 36... The Lowest Common Multiple for 4 and 6 is 12.  
Square Number  A number that results from multiplying another number by itself. Ex 25 is the square of 5.  
Square Root  A number which, when multiplied by itself, gives the original number. Ex 5 is the square root of 25. 
Exponent  A small number placed to the upper right of a number that shows how often the base number is multiplied by itself.  
Base The factor repeated in a power. Ex 7 to the power 2, is 7x7. 7 is the base.  
Power  An expression of a product of equal factors. Ex 4x4x4 can be expressed as 4 to the power 3, 4 is the base and 3 is the exponent.  
Cube Number  A power (number) with exponent 3. To raise to the third power, or a number multiplied by itself three times. Ex 4 cubed is 4x4x4=64  
Exponent Form  When numbers are repeated in multiplication. Ex 9 to the power 3, means 9x9x9.  
Perfect Square  A number that is the square of a whole number. Ex 16 is a perfect square because 16 = 4 to the power 2.  
Perfect Cube  A number that is the cube of a whole number. Ex 64 is a perfect cube because 64 = 4 to the power 3.  
Range  difference between the smallest and largest number in a set of data
