Math question: What is the sum of the prime factors of the number 9890?

To find the prime factors of 9890, we break it down into its prime factors: 2, 5, 197. The sum of these prime factors is 2 + 5 + 197 = 204. Therefore, the sum of the prime factors of 9890 is 204.

What is the largest prime number that is less than 9890?

The largest prime number less than 9890 is 9887. To find this, we start checking from 9890 descending to lower numbers until we find a prime. We can divide 9890 by each number, starting from 9889 and moving downwards. When we reach 9887, we find that it is only divisible by 1 and itself, making it a prime number. Hence, 9887 is the answer.

Math question: What is the sum of the prime factors of the number 9890?

To find the prime factors of 9890, we start by dividing it by the smallest prime number, 2. The quotient is 4945. By dividing 4945 by 5, we obtain 989, which cannot be divided evenly by 2 or 5 anymore. Next, dividing 989 by the prime number 7, we get a quotient of 141. However, 141 is also not divisible by 2, 3, 5, or 7. Finally, dividing 141 by the prime number 11, we obtain a quotient of 13, which is a prime number. Now we have found all the prime factors of 9890: 2, 5, 7, and 11. To find the sum, we add them all up: 2 + 5 + 7 + 11 = 25. The sum of the prime factors of the number 9890 is 25.
