Question

Find the common factors of:

$4,8$ and $12$

Answer 1

Find the common factors of given numbers:

A number is said to be a factor of a given number if it divides the given number exactly.

A factor is said to be common factor of two numbers if, it is a factor of both.

Factors of $4$ are $1,2$ and $4$, because they all divide $4$.

Factors of $8$ are $1,2,4$ and $8$, because they all divide $8$.

Factors of $12$ are $1,2,3,4,6$ and $12$, because they all divide $12$..

From above, we conclude that common factors of $4,8$ and $12$ are $1,2$ and $4$ .

Therefore, $1,2$ and $4$ are common factors of $4,8$ and $12$.
