LCM and HCF Practice Test 3

Concept:The HCF of algebraic terms is the product of the lowest powers of variables common to all terms.Explanation:List the variables in each expression:First term: $x^5 \times y^2 \times z^1$ has $x, y, z$.Second term: $v^2 \times w^1 \times x^4$ has $v, w, x$.Third term: $u^1 \times v^1 \times w^2$ has $u, v, w$.Check for a variable present in all three terms.$x$ is not in the third term.$v$ is not in the first term.$w$ is not in the first term.No variable is common to all three expressions.Therefore, the HCF is $1$.Answer:$1$
