Step 1: Find the prime factorizations of the numbers:
- For 10500:
10500=2^2\cdot3^1\cdot5^3\cdot7^1
- For 38808:
38808=2^3\times3^2\times7^2\times11^1
Step 2: Determine the LCM by taking the highest power of each prime factor that appears in any of the factorizations:
- For prime 2: highest power is 2^3
- For prime 3: highest power is 3^4
- For prime 5: highest power is 5^4
- For prime 7: highest power is 7
- For prime 11: highest power is 11
Step 3: Multiply these together to get the LCM:
\text{LCM}=2^3\times3^2\times5^3\times7^2\times11^1
Step 4: Calculate the value:
2^3=8,\quad3^2=9,\quad5^3=125,\quad7^2=49,\quad11^1=11
\text{LCM}=8\times9\times125\times49\times11=4851000
