FACTORS -

Definition- A number is a factor of a given number if it divides that number exactly, without any remainder.

5 x 7 = 35

35 ÷ 5 = 7

35 ÷ 7 = 5

5 and 7 are divisors of 35 as they divide 35 without any remainder.

∴ 5 and 7 are called the factors of 35.

A factor is a number which divides a given number exactly.

4 x 12 = 48;        4 and 12 are the factors of 48.

8 x 9 = 72;         8 and 9 are the factors of 72.

Example.1) Is 9 a factor of 439 ?

Ans.)

9 is not a factor of 439 since the remainder is not 0.  (Ans.)

Example.2)  Is 8 a factor of 585 ?

Ans.) 

8 is not a factor of 585 since the remainder is not 0.   (Ans.)
