Math question: What is the sum of 3191 divided by 7, multiplied by 4, subtracted by 821, and then divided by 2?

To find the answer, we calculate step by step. First, 3191 divided by 7 equals 455.857. Multiplying this by 4 gives us 1823.429. Subtracting 821 from this result leaves us with 1002.429. Finally, dividing 1002.429 by 2 leads to an answer of 501.2145. Thus, the answer is 501.2145.

Math question: What is the sum of the digits in the number 3191?

To find the sum of the digits, we add the individual digits together. In 3191, we have 3 + 1 + 9 + 1, which equals 14. Thus, the sum of the digits in 3191 is 14.

Math question: What is the sum of the even factors of 3191?

To find the even factors, we need to determine the prime factorization of 3191: 3191 = 61 * 53. Next, we consider each factor pair (61, 1) and (53, 1). The even factors are obtained by multiplying the prime factors with 2. Hence, the even factors are (122, 2) and (106, 2). The sum of these even factors is 122 + 2 + 106 + 2 = 232. Therefore, the sum of the even factors of 3191 is 232.
