Least Common Multiple
(LCM) |
the smallest number that all numbers can become - uses the cake method (never smaller than the biggest number)
|
|
Greatest Common Factor
(GCF) |
the biggest number that all of the numbers can be divided by - uses the tree method (never bigger than the smallest number)
|
|
factor
|
a number that divides another number without a remainder (always equal to or smaller than the original number)
ie. factors of 24 = 1, 2, 3, 4, 6, 8, 12, 24 |
|
multiple
|
the product of the original number and another number (always equal to or larger than the original number)
ie. multiples of 5 = 5, 10, 15, 20, 25 |
|
ascending order
|
from smallest to biggest
|
|
descending order
|
from biggest to smallest
|
|
absoute value
|
the distance the number is from zero on a number line - the distance can NEVER be negative
|
|
composite number
|
a whole number that has factors besides 1 and itself - the smallest composite number is 4
|
|
prime number
|
a whole number whose only factors are 1 and itself - 2 is the smallest prime and the ONLY even prime
|
|
coordinate pairs
|
used in graphing - (x,y) - the first number tells you right or left; the second number tells you up or down
|
|
divisibility rule for 2
|
if the number ends in 0, 2, 4, 6, or 8
|
|
divisibility rule for 5
|
if the number ends in 0 or 5
|
|
divisibility rule for 6
|
if it is divisible by BOTH 2 and 3
|
|
divisibility rule for 10
|
if it ends in 0
|
|
divisibility rule for 3
|
if the sum of the digits adds up to a number divisibile by 3
ie. 123 = 1 + 2 + 3 = 6; 6 is divisibile by 3 so 123 is divisible by 3 |
|
divisbility rule for 9
|
if the sum of the digits is divisible by 9
ie. 63 = 6 + 3 = 9; 9 is divisible by 9 so 63 is divisible by 9 |
|
equivalent
|
equal
|
|
