Math question: What is the largest prime factor of the number 9907?

To find the largest prime factor of 9907, we can start by checking the divisibility of 9907 by prime numbers. First, 9907 is not divisible by 2 since it is an odd number. Then, dividing 9907 by 3 results in a quotient with a fractional part, meaning it is not divisible by 3. Similarly, trying the next few prime numbers reveals that 9907 is not divisible by 5, 7, or 11. However, when dividing 9907 by 13, we find that it is divisible evenly. Continuing the division process, we find that the quotient, after dividing by 13, is 761. Interestingly, this quotient is prime. Therefore, the largest prime factor of 9907 is 761.

Math Question: The number 9907 is divided by a two-digit number and the quotient is equal to the product of the two digits. What is the two-digit number?

Let's assume the two-digit number is xy, where x represents the tens digit and y represents the units digit. According to the given condition, we have the equation: 9907 ÷ xy = 10x + y. Simplifying this equation, we get 9907 = xy(10x + y). Now, let's analyze the possible values of x and y to satisfy this equation: Case 1: If x = 0, the equation becomes 9907 = y^2, which has no solution since y^2 can't be equal to 9907. Case 2: If x ≥ 1, 10x + y must be a divisor of 9907. By checking divisors of 9907, we find that 99 is the only divisor able to satisfy this condition. Thus, the two-digit number is 99.

Math question: What is the product when 9907 is multiplied by the sum of its digits?

To find the product, we first need to calculate the sum of the digits in 9907. The sum is obtained as 9 + 9 + 0 + 7 = 25. Next, multiply 9907 by the sum of its digits: 9907 * 25 = 247,675. Hence, the product of 9907 and the sum of its digits is 247,675.
