Question 87 (vii)

Write the greatest common factor in the following terms.

$3x^3{y}^{2}z,-6x{y}^3{z}^2,12x^{2}y{z}^3$

Answer 1

We have,
$3x^3{y}^{2}z=3\times x\times x\times x\times y\times y\times z$
$-6x{y}^3{z}^2=-1\times 3\times 2\times x\times y\times y\times y\times z\times z$
$12x^{2}y{z}^3=3\times 4\times x\times x\times y\times z\times z\times z$
$\therefore GCF=3xyz$
