Factors and multiples (Notes)

Factors and multiples

Factors:-

Factors are the numbers we can multiply together to get another number.

A factor of a number divides that number exactly.

Example: find the factors of 12

  pair 1: 1*12

  pair 2: 2*6

  pair 3: 3*4

(In all the four cases the remainder is 0 if we will divide them)

Here 1,2,3,4,6,12 all are factors of 12.

Remember-

1.Every number has 1 as a factor.

2.Every number is a factor of itself.

3.Every number (except 1) has at least two factors, 1 and the number itself. 

4.The factors of a number is always equal to or less than the number.

Multiples:-

A multiple of a number is the product obtained when the given number is multiplied by the same or any other number.

Example,

Find the multiples of 12.

12*1=12

12*2=24

12*3=36

and so on.

This all products we got by multiplying with 12(12,24,36,48...) is called multiples of 12.

Remember-

1.A number is a multiple of itself.

2.Every number is a multiples of 1.

3.Every multiples of a given number is equal to or greater than the number itself.

4.Every number has infinite numbers of multiples.

5.0 is a multiple of every number. But 0 is not a factor of any number except 0.
