What is the sum of all the even factors of 8780?

To find the sum of the even factors of 8780, we first need to find all the factors of 8780. The factors of a number are the numbers that divide it evenly. The prime factorization of 8780 is 2^2 × 5 × 439. So, the factors of 8780 are: 1, 2, 4, 5, 10, 20, 439, 878, 1756, and 4390. Out of these factors, the even factors are: 2, 4, 10, 20, 878, 1756, and 4390. To find their sum, we add these numbers together: 2 + 4 + 10 + 20 + 878 + 1756 + 4390 = 9060. Therefore, the sum of all the even factors of 8780 is 9060.

Math question: What is the sum of the prime factors of 8780?

To find the prime factors of 8780, we prime-factorize the number as 2² × 5 × 439. Therefore, the sum of the prime factors is 2 + 2 + 5 + 439 = 448.

What is the sum of all the odd numbers between 8780 and 1 inclusive? Express your answer in scientific notation rounded to 4 decimal places.

The sum of odd numbers can be calculated using the formula n * (n + 1), where n is the number of odd terms. There are (8780 - 1)/2 + 1 = 4390 odd numbers between 8780 and 1. Thus, the sum is 4390 * (4390 + 1) = 19306845. Expressing it in scientific notation gives approximately 1.9307 x 10^7.
