Factors and Multiples

We had a lot of fun learning about factors and multiples today in math! Here is a fun song that we listened to, to help us remember factors!

Here’s another nice link to review with your child:

Be sure to ask your child what the definition for each are:

FACTORS

Factors are numbers you can multiply together to get another number: Example: 2 and 3 are factors of 6, because 2 × 3 = 6. A number can have MANY factors!

Example: Factors of 6 are 1, 2, 3, 6 (1×6=6, 6×1=6, 2×3=6 and 3×2=6)

For larger numbers it is sometimes easier to ‘pair’ the factors by writing them as multiplications.

For example, 24 = 1 x 24 = 2 x 12 = 3 x 8 = 4 x 6

So the factors of 24 are 1, 2, 3, 4, 6, 8, 12 and 24.

MULTIPLES

A multiple is the product of two numbers multiplied together. For example, the first five multiples of 3 (your given number) are 0, 3, 6, 9 and 12.

Multiples are really just extended times tables. You can think of them as skip counting (starting with 0) by the number you are given.

Another example:

First 5 multiples 4 are:

0x4=0

1×4=4

2×4=8

3×4=12

4×4=16

So the first 5 multiples of 4 are 0, 4, 8, 12 and 16.
