Question

Find the GCF : (7x^2y ,x^2y^2,21x^4y^2)

Answer 1

The given expressions are

`7x^2y,x^2y^2,21x^4y^2`

We have to find the greatest common factor of the coefficients and variables.

The Greatest Common Factor between coefficients is 7 because that's the highest factor that's common.

The Greatest Common Factor between variables is

`x^2y`

Hence, the GCF is

`7x^2y`
