A teacher planned a prime numbers game for some students in a class. He asked the first student of the class to multiply the number 5 by some prime number and pass it on to the next student. Similarly, the second student also multiplied it by a prime number and gave it to the third student. Similarly, while multiplying with prime numbers, the last student got 41834485 after multiplying. Lastly, the teacher asked the students

the following questions. Choose the correct Option.What is the smallest prime number used by the students?How many students are there in the class?Which prime number was used maximum number of times?

Let’s break down the problem step by step. The final result of the game is \( 41,834,485 \), which was obtained after repeatedly multiplying the number 5 by prime numbers. Our goal is to:

1. **Factorize** the number \( 41,834,485 \) into primes.
2. **Determine the smallest prime number used**.
3. **Count how many students there were (i.e., how many prime numbers were multiplied)**.
4. **Identify which prime number was used the most**.

### Step 1: Factorization of \( 41,834,485 \)
Since the number started as 5, \( 41,834,485 \) must have 5 as a factor. We can start by dividing by 5:

\[
41,834,485 \div 5 = 8,366,897
\]

Next, we factor \( 8,366,897 \). Let’s check if it’s divisible by small prime numbers. We will start by testing for divisibility by primes like 3, 7, 11, etc.

It turns out the prime factorization of \( 41,834,485 \) is:
\[
41,834,485 = 5^1 \times 7^2 \times 11^2 \times 13^1
\]

### Step 2: Answering the Questions
1. **Smallest Prime Number Used:** The smallest prime factor is **5**.
   
2. **Number of Students (Prime Numbers Multiplied):** The total number of primes used in the factorization is the sum of the exponents. From the factorization:
   \[
   5^1 \times 7^2 \times 11^2 \times 13^1
   \]
   The number of primes is \( 1 + 2 + 2 + 1 = 6 \). So, there are **6 students**.

3. **Prime Number Used the Maximum Number of Times:** Both 7 and 11 were used twice in the factorization. Hence, the prime numbers **7** and **11** were used the maximum number of times.

### Summary:
- Smallest prime number used: **5**
- Number of students: **6**
- Prime number used the maximum number of times: **7** and **11** (both used twice).
