Question

Choose the HCF of 6xy^3 and 9x^2y

Answer 1

Answer:

3xy

Step-by-step explanation:

$6x {y}^{3} = 2 \times 3 \times x \times y \times y \times y \\ 9 {x}^{2} y = 3 \times 3 \times x \times x \times y \\ \\ common \: factors = 3, \: x, \: y \\ \therefore \: HCF = 3\times x\times y\\\therefore \: HCF = 3xy$
