Math Problem Statement
Solution
The question in the image asks:
"What is the maximum power of n such that n divides 500! (500 factorial)?"
This is a typical problem of finding the largest exponent such that a number divides .
Step-by-Step Solution:
Let’s assume is a prime number. To find the highest power of a prime that divides , we use Legendre’s formula (also called de Polignac's formula):
Where denotes the greatest integer less than or equal to , and is the successive powers of the prime .
The steps are:
- Divide 500 by (the prime number).
- Divide the result by again (repeating until the division is zero).
- Sum all the quotients (rounded down).
If is a composite number, first factorize it into primes and apply the formula to each prime factor separately.
If you provide a specific value for , I can compute the answer for that prime or composite number.
Would you like more details or help with a specific value of ?

- What is the highest power of 2 that divides 500!?
- Can we apply the same method to non-prime values of ?
- What role do prime numbers play in this type of divisibility problem?
- How would the solution change if the factorial were a different number, like 1000!?
Tip: For composite numbers, always break them down into their prime factors before applying Legendre’s formula!
