Math question: What is the sum of all integer divisors of 208?

To find the sum of divisors, we start by finding the prime factorization of 208: 2^4 * 13. The divisors of 208 are formed by taking the product of various powers of the prime factors. They are: 1, 2, 4, 8, 13, 16, 26, 52, 104, and 208. Now, we sum these divisors to obtain 444. Thus, the sum of all integer divisors of 208 is 444.

Math question: What is the sum of the even numbers from 1 to 208?

To find the sum, we need to determine the number of even numbers between 1 and 208. Since an even number occurs every second number, we can divide 208 by 2 to get 104. This means there are 104 even numbers between 1 and 208. Now we can calculate the sum using the formula for the sum of an arithmetic series: S = (n/2)(first term + last term), where n is the number of terms. The first even number is 2 and the last is 208. Plugging in the values, we have S = (104/2)(2 + 208) = 52(210) = 10,920. Therefore, the sum of the even numbers from 1 to 208 is 10,920.

Math question: What is the sum of all the even numbers from 2 to 208, inclusive?

To find the sum of all even numbers from 2 to 208, we use the arithmetic series formula. The first term (a) is 2, the last term (l) is 208, and the common difference (d) is 2 since these are consecutive even numbers. The formula for the sum of an arithmetic series is Sn = (n/2) * (a + l), where n is the number of terms. To find the number of terms, we can use the formula n = (l - a) / d + 1. Substituting the values, n = (208 - 2) / 2 + 1 = 104. So, Sn = (104/2) * (2 + 208) = (52) * (210) = 10,920. Hence, the sum of all the even numbers from 2 to 208 is 10,920.
