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**.

Here are five related questions you could explore:
1. What is the difference between LCM and GCD (Greatest Common Divisor)?
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.
