Question

Which of the following is not a factor of $5xy$?

• A. $y^2$
• B. $xy$
• C. $5x$
• D. $x$

Answer 1

The correct option is A $y^2$

$5xy=5\times x\times y$

The factors of $5xy$ are $1,5,x,y,5x$ (product of $5$ and $x$), $5y$ (product of $5$ and $y$), $xy$ (product of $x$ and $y$), and $5xy$.
