Math Question: What is the sum of all the even factors of 9911, excluding the number itself?

To find the sum of even factors of 9911, we need to determine all the factors of 9911 first. Since the given number is a prime, it has only two factors, 1 and 9911. As there are no even factors (excluding the number itself), the sum equals zero.

Question: Find the sum of the digits of the number 9911 and multiply it by the difference between the sum of the digits and the product of the digits. What is the answer?

First, find the sum of the digits: 9 + 9 + 1 + 1 = 20. Next, find the product of the digits: 9 * 9 * 1 * 1 = 81. Now, calculate the difference: 20 - 81 = -61. Finally, multiply the sum by the difference: 20 * -61 = -1220. Therefore, the answer is -1220.

Math question: How many prime factors does the number 9911 have?

To find the number of prime factors, we need to factorize 9911. Checking divisibility, we observe it is not divisible by 2, 3, 5, or 7. Now, we test division by prime numbers greater than 7. By dividing 9911 successively by primes, we find that it is only divisible by itself. Therefore, 9911 is a prime number and has only one prime factor.
