Factors/Multiples

Factors-the multiplication facts that give you the value you are looking for. Every number has 1 and itself as a factor. 

     Example 1:The factors of 10, so 1 and 10

                                                      2 and 5

                      The factors of 10 are 1,2,5, and 10

 

     Example 2: Factors of 25- 1 and 25

                                             5 and 5, but you only use 5 once

                     The factors of 25 are 1,5,25

 

 

 

Multiples- you need to multiply the number as many times as the question asks

    Example 1:What are the first 4 multiples of 2

                                                                                  2x1=2

                                                                                  2x2=4

                                                                                 2x3=6

                                                                                 2x4=8

                                          The first four multiples of 2 are 2, 4, 6, and 8

        Example 2: What are the first 6 multiples of 6?

                                 6x1=6

                                 6x2=12

                                 6x3=18

                                 6x4=24

                                 6x5=30

                                 6x6=36

                        the first 6 multiples of 6 are 6, 12, 18, 24, 30, 26
