Math question: If a number is divided by 9, the quotient is 903 and the remainder is the same as the divisor, what is the number?

Let's assume the unknown number is x. According to the division algorithm, we can write the equation: 9 * 903 + x = 8131. Simplifying, we have 8137 + x = 8131. By subtracting 8137 from both sides, we get x = -6. Therefore, the number is -6.

Math question: What is the largest prime factor of the number 8131?

To find the largest prime factor of 8131, we first need to find its prime factorization. Dividing 8131 by the smallest prime number, 2, leaves us with 4065. Continuing the process, dividing 4065 by 3 results in 1355. Dividing 1355 by 5 gives us 271. Although 271 is also not divisible by 2 or 3, it is a prime number itself. Therefore, the largest prime factor of 8131 is 271.

Math question: What is the sum of the digits in the number 8131?

To find the sum of the digits in the number 8131, we add each digit together. The digit 8 + 1 + 3 + 1 equals 13. Therefore, the sum of the digits in the number 8131 is 13.
