Question

36a2b2c2, 27a2b2c2, and 72abc

Answer 1

Answer:

$\\ 36 {a}^{2} {b}^{2} {c}^{2} \\ = 3 \times 3 \times 4 \times {a}^{2} {b}^{2} {c}^{2}$

and

$\\ 27 {a}^{2} {b}^{2} {c}^{2} \\ = 3 \times 3 \times 3 \times {a}^{2} {b}^{2} {c}^{2}$

And finally,

$\\ 72abc \\ = 3 \times 3 \times 2 \times 2 \times 2 \times abc$

The HCF of above polynomials is,

$\: hcf = 3 \times 3 \times abc \\ = 9abc$
