Find the highest common factor of;
$7x^2yz^4, 21x^2y^5z^3$

Given:

$7x^2yz^4, 21x^2y^5z^3$

To Do: Find the highest common factor

Solution:

Factors of $7x^2yz^4, 21x^2y^5z^3$

$7 x^2yz^4 = 7\times x^2\times y\times z^4$

$21x^2y^5z^3$= $3\times7\times x^2\times y^5\times z^3$

From the above factors of 

$7x^2yz^4, 21x^2y^5z^3$

Therefore, HCF of $7x^2yz^4, 21x^2y^5z^3$

= $7x^2yz^3$
