Question

Which among the following is not a factor of $24x^{2}y?$

• A. $12x^2$
• B. $12y$
• C. $9xy$
• D. $3x^{2}y$

Answer 1

The correct option is C $9xy$

The factors of a number are all the numbers that divide it completely.

Hence, the factors of $24x^2{y}^{3}z$ are all the numeric factors, i.e., 1, 2, 3, 4, 6, 8, 12, and 24.

Other factors that include variables:

$x,2x,3x,4x,6x,8x,12x,24x$

$y,2y,3y,4y,6y,8y,12y,24y$

$x^2,2x^2,3x^2,4x^2,6x^2,8x^2,12x^2,24x^2$

$xy,2xy,3xy,4xy,6xy,8xy,12xy,24xy$

$x^{2}y,2x^{2}y,3x^{2}y,4x^{2}y,6x^{2}y,8x^{2}y,12x^{2}y,24x^{2}y$
