Question: If 3904 is divided by the sum of its digits, what is the quotient?

The sum of the digits in 3904 is 3+9+0+4 = 16. Therefore, when we divide 3904 by 16, the quotient is 244 with a remainder of 0. So, the quotient of 3904 divided by the sum of its digits is 244.

Question: What is the sum of the first 50 even numbers greater than 3900?

To find the sum of the first 50 even numbers greater than 3900, we first determine the smallest even number greater than 3900, which is 3902. Then, we add 2 repeatedly to obtain the sequence: 3902, 3904, 3906, 3908, ..., 4048. Now, using the formula for the sum of an arithmetic series, the general term of the sequence is given by an = 3902 + 2(n - 1). We have an arithmetic series with a common difference of 2 and n = 50. Plugging these values into the formula, S = n/2(2a1 + (n - 1)d), where S represents the sum, a1 the first term, and d the common difference. Therefore, S = 50/2(2(3902) + (50 - 1)2) = 25(7804 + 98) = 25(7902) = 197,550. Hence, the sum of the first 50 even numbers greater than 3900 is 197,550.

Question: What is the sum of the squares of the prime factors of 3904?

To find the prime factors of 3904, we first know it is divisible by 2 four times (2^4). By dividing 3904 by 2 repeatedly, we get 487. Then, we divide 487 by 17, resulting in 29. Therefore, the prime factors are 2 and 17. Now, we square each prime factor and add them together: (2^2) + (17^2) = 4 + 289 = 293. Thus, the sum of the squares of the prime factors of 3904 is 293.
