Factors & Multiples

08 Oct

Factors and multiples can be scary word if you don’t understand their meaning.

A factor is simply taking apart a number so that it is expressed as a product of the factor. Factors can also be either a composite number or a prime number (0 and 1 are neither.)

The Prime numbers are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37,…..

Prime numbers can be defined as a number greater than one who’s only factors are one and  itself.

The Composite number are: 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20,……

Composite numbers can be defined as counting number that are not prime.

For example: 16

The factors of 16 are 1,16; 2,8; and 4

therefore we can take one of these factor pairs; such as 2,8 and write a multiplication problem. 2 X 8 = 16

Multiples are a number of a product;that number and any other whole number. Zero is a
multiple of every number.

For example: 12 is a multiple of 3 because 3 divides evenly.

So 3 x 4 = 12 ; 12 is a multiple of 3 and 4.
