(A) To find the $LCM$ of $6$ and $20$,we first find their prime factorizations:$6 = 2 \times 3$$20 = 2^2 \times 5$The $LCM$ is the product of the highest powers of all prime factors involved:$LCM = 2^2 \times 3^1 \times 5^1$$LCM = 4 \times 3 \times 5 = 60$Therefore,the $LCM$ of $6$ and $20$ is $60$.
