• Mode

• Median

• Least Common Multiple

• Factor Tree

Mode

• The definition of mode is: the number or range of numbers in a mathematical set that occurs the most frequently.

• A example is: 13,29,30,12,13,13,28,30,12,12,13

The mode is: 13 because it occurred most frequently in this set of data.

Median

• The definition of median is: the middle value in a set of numbers arranged in an increasing order. If there is an even number of values, then median is the average of the middle two values.

• An example of median is: 11,19,21,29,49.

• The middle number is 21 so 21 is the median.

Least Common Multiple

• The definition of least common multiple is: the least common multiple of 2 numbers is the smallest number they both divide evenly into. One good way to find the LCM of 2 numbers is to multiply both numbers by 1,2,3,4, and 5…. And then find the first multiple that appears in both lists.

• An example is:10:20,30,40,50,60,70,80,90,100,110,120

• 24:48,72,96,120

Factor trees• The definition of a factor tree is: a special diagram where you find

the factors of a number, then the factors of those numbers, etc., until you cant FACTOR anymore, and the result is all the prime factors of the original number.

• A example of a factor tree is:

• 42 / \ 2 21 / \ 3 7
