The correct Answer is:
To find the number of divisors of the number 36,000, we will follow these steps: ### Step 1: Prime Factorization of 36,000 We start by performing the prime factorization of 36,000. 1. **Break down 36,000**: \[ 36,000 = 36 \times 1,000 \] 2. **Factor 36**: \[ 36 = 6 \times 6 = (2 \times 3) \times (2 \times 3) = 2^2 \times 3^2 \] 3. **Factor 1,000**: \[ 1,000 = 10^3 = (2 \times 5)^3 = 2^3 \times 5^3 \] 4. **Combine the factors**: \[ 36,000 = 36 \times 1,000 = (2^2 \times 3^2) \times (2^3 \times 5^3) \] 5. **Combine like bases**: \[ 36,000 = 2^{2+3} \times 3^2 \times 5^3 = 2^5 \times 3^2 \times 5^3 \] ### Step 2: Use the Formula for Divisors The formula to find the number of divisors \(d(n)\) of a number \(n = p_1^{e_1} \times p_2^{e_2} \times p_3^{e_3}\) is: \[ d(n) = (e_1 + 1)(e_2 + 1)(e_3 + 1) \] where \(e_1, e_2, e_3\) are the powers of the prime factors. 1. **Identify the powers**: - For \(2^5\), the power is \(5\). - For \(3^2\), the power is \(2\). - For \(5^3\), the power is \(3\). 2. **Apply the formula**: \[ d(36000) = (5 + 1)(2 + 1)(3 + 1) \] \[ = 6 \times 3 \times 4 \] ### Step 3: Calculate the Result 1. **Calculate the product**: \[ 6 \times 3 = 18 \] \[ 18 \times 4 = 72 \] ### Final Answer The number of divisors of the number 36,000 is **72**. ---
