Math question: What is the sum of all the divisors of 1008?

To find the sum of all divisors of 1008, first factorize it. 1008 can be expressed as 2^4 * 3^2 * 7. Now, using the formula for sum of divisors, multiply the powers of prime factors by one less than their consecutive powers, i.e., (4+1)(2+1)(1+1) = 5 * 3 * 2 = 30. Hence, the sum of divisors is 30.

Math question: What is the ratio of the sum of the even divisors of 1008 to the sum of the odd divisors of 1008?

To find the even divisors of 1008, we note that it can be factored as 2^4 * 3^2 * 7. Listing out all possible combinations of these prime factors gives us a total of (4+1)(2+1)(1+1) = 30 divisors, including even and odd ones. Among these, 15 divisors are even (2, 4, 8, ..., 1008), and the remaining 15 are odd (1, 3, 9, ..., 1008). The sum of even divisors can be calculated using the formula for the sum of a geometric series: (2+4+8+...+1008) = 2*(2^15 - 1). Similarly, the sum of odd divisors is (1+3+9+...+1008) = 3*(3^7 - 1). Thus, the ratio of the sum of even divisors to the sum of odd divisors is (2*(2^15 - 1))/(3*(3^7 - 1)). Evaluating this expression yields the answer.

Math question: What is the product of the prime factors of 1008, excluding the number 1?

To find the prime factors of 1008, we start by dividing it by the smallest prime number, which is 2. We get 504. Continuing this process, we divide 504 by 2 to get 252, then divide 252 by 2 to get 126, and so on. Finally, we divide 126 by 2 to get 63. Now we start dividing by the next prime number, which is 3. Dividing 63 by 3 gives us 21, and then dividing 21 by 3 gives us 7. Notice that 7 is a prime number and we cannot divide further. So, the prime factors of 1008 are 2, 2, 2, 2, 3, 3, 7. Their product is 2 × 2 × 2 × 2 × 3 × 3 × 7 = 2016.
