Question

Find the common factors of the following term​

Answer 1

Given:

We have numbers $7m^2n,7mn,9mn^2,7m^2n^2$.

To Find:

We have to find common factors.

Step-by-step explanation:

• First of all we find prime factors of al numbers

• Prime factor of $7m^2n$=$7\times m\times m\times n$

• Prime factor of $7mn$=$7\times m\times n$

• Prime factor of $9mn^2$=$9\times m\times n\times n$

• Prime factor of $7m^2n^2$=$7\times m\times m\times n\times n$

               Now common factor of all numbers is m

Thus, common factor is m.
