Question

The H.C.F. of $3x{y}^2{z}^3$, $3y{z}^2{x}^2$ and $x^2{y}^{2}z$ is .

• A. $x^{2}yz$
• B. $3x{y}^2{z}^3$
• C. $xyz$
• D. $x^2{y}^{2}z$

Answer 1

The correct option is C $xyz$

In the three given quantities, the common factors are x, y and z. The highest powers of x, y and z that exactly divide the given quantities are $x^1,y^1$ and $z^1$ respectively.
