The image provided is a quiz question, which appears to ask for the least common multiple (LCM) of the numbers 3, 5, 10, and 25. I'll solve it for you:

To find the LCM of multiple numbers, we follow these steps:

1. Prime factorization of each number:

   • $3$ is already a prime number.
   • $5$ is also a prime number.
   • $10 = 2 \times 5$.
   • $25 = 5^2$.

2. Take the highest power of each prime factor from the factorizations:

   • For 3: The highest power is $3^1$.
   • For 5: The highest power is $5^2$.
   • For 2: The highest power is $2^1$.

3. Multiply these highest powers: $LCM = 3^1 \times 5^2 \times 2^1 = 3 \times 25 \times 2 = 150.$

So, the least common multiple of 3, 5, 10, and 25 is 150.

2. How can you find the LCM using a different method like listing multiples?
3. What is the LCM of three numbers: 8, 12, and 20?
4. Can LCM be smaller than any of the numbers given?
5. How does LCM apply to real-world problems like scheduling or synchronization?

Tip: When working with prime factorization, always ensure to include the highest powers of all primes involved for accurate LCM results.
