Math Question: What is the sum of the factors of 8990?

To find the sum of the factors of 8990, we first need to find all the factors. The prime factorization of 8990 is 2 × 5 × 17 × 53. Therefore, the factors of 8990 are 1, 2, 5, 10, 17, 34, 53, 85, 106, 170, 265, 530, 985, 1990, 4975, and 8990. Adding these factors together, we obtain a sum of 18798. Hence, the sum of the factors of 8990 is 18798.

Math question: What is the largest prime factor of the number 8990?

To find the largest prime factor of 8990, we can start by dividing it by the smallest prime number, 2. We get 4495. Continuing this process, we divide it by 5, which gives 899, and then by 13, which leaves us with 69. As 69 can be broken down into 3 × 23, we conclude that the prime factorization of 8990 is 2 × 5 × 13 × 3 × 23. Among these factors, the largest prime number is 23. Therefore, the largest prime factor of 8990 is 23.

Math question: What is the sum of all the digits in the number 8990?

To find the sum of the digits in the number 8990, we add up each individual digit: 8 + 9 + 9 + 0 = 26. Therefore, the sum of the digits in the number 8990 is 26. The sum of digits is a useful concept in number theory and can provide valuable insight into the properties of a given number, such as divisibility or patterns in its digital root. In this case, the number 8990 has a digit sum of 26, thereby indicating that it is not divisible by the digit sum 9 (since 26 is not divisible by 9) and has no patterns in its digital root.
