The correct Answer is:
To solve the problem of showing that \(2^{16}\) divides \(32!\) and finding the highest power of \(2\) that divides \(32!\), we will use the formula for finding the highest power of a prime \(p\) that divides \(n!\): \[ \text{Highest power of } p \text{ in } n! = \left\lfloor \frac{n}{p} \right\rfloor + \left\lfloor \frac{n}{p^2} \right\rfloor + \left\lfloor \frac{n}{p^3} \right\rfloor + \ldots \] ### Step-by-step Solution: 1. **Identify the values**: Here, \(n = 32\) and \(p = 2\). 2. **Calculate each term**: - First term: \[ \left\lfloor \frac{32}{2} \right\rfloor = \left\lfloor 16 \right\rfloor = 16 \] - Second term: \[ \left\lfloor \frac{32}{2^2} \right\rfloor = \left\lfloor \frac{32}{4} \right\rfloor = \left\lfloor 8 \right\rfloor = 8 \] - Third term: \[ \left\lfloor \frac{32}{2^3} \right\rfloor = \left\lfloor \frac{32}{8} \right\rfloor = \left\lfloor 4 \right\rfloor = 4 \] - Fourth term: \[ \left\lfloor \frac{32}{2^4} \right\rfloor = \left\lfloor \frac{32}{16} \right\rfloor = \left\lfloor 2 \right\rfloor = 2 \] - Fifth term: \[ \left\lfloor \frac{32}{2^5} \right\rfloor = \left\lfloor \frac{32}{32} \right\rfloor = \left\lfloor 1 \right\rfloor = 1 \] - Sixth term: \[ \left\lfloor \frac{32}{2^6} \right\rfloor = \left\lfloor \frac{32}{64} \right\rfloor = \left\lfloor 0.5 \right\rfloor = 0 \] 3. **Sum the terms**: \[ 16 + 8 + 4 + 2 + 1 = 31 \] 4. **Conclusion**: The highest power of \(2\) that divides \(32!\) is \(31\). Since \(31 > 16\), we can conclude that \(2^{16}\) divides \(32!\). ### Final Answer: - The highest power of \(2\) that divides \(32!\) is \(31\). - Therefore, \(2^{16}\) divides \(32!\).
