To find the Least Common Multiple (LCM) of three numbers, we look at the prime factorization of each number and take the highest power of each prime factor present in any of the numbers.

Given the numbers are in factored form, let’s break them down first:

1. Number 1: $2^3 \times 3^2 \times 5 \times 11$
2. Number 2: $2^4 \times 3^4 \times 5^2 \times 7$
3. Number 3: $2^5 \times 3^3 \times 5^3 \times 7^2 \times 11$

Step-by-Step Process for LCM:

We now find the highest powers of each prime factor across the three numbers:

• For 2: The highest power is $2^5$.
• For 3: The highest power is $3^4$.
• For 5: The highest power is $5^3$.
• For 7: The highest power is $7^2$.
• For 11: The highest power is $11$.

Thus, the LCM is: $LCM = 2^5 \times 3^4 \times 5^3 \times 7^2 \times 11$

This matches option D: $2^5 \times 3^4 \times 5^3 \times 7^2 \times 11$.

Answer:

The correct option is D.
