Math question: What is the largest prime factor of the number 4385?

To find the largest prime factor of 4385, we start by finding the prime factors of the number. Dividing 4385 by 2, we get 2192.5. Since this is not a whole number, 2 is not a factor. Next, dividing 4385 by 3, we obtain 1461.67, which is not a whole number either. Continuing this process, we divide by 5, obtaining 877, which is a whole number. Thus, 5 is a prime factor of 4385. Now, we divide 877 by 7, obtaining 125.29, which is not a whole number. Next, dividing 877 by 11, we get 79.73, which is also not a whole number. Finally, dividing by 13, we get 67, which is a whole number. Hence, the largest prime factor of 4385 is 13.

Math question: What is the sum of the digits in the number 4385?

To find the sum of the digits in 4385, we add each digit individually. The digits are 4, 3, 8, and 5. Adding them together, we get 4 + 3 + 8 + 5 = 20. Therefore, the sum of the digits in 4385 is 20.

Math question: If you divide the number 4385 by 5 and then multiply the result by 9, what is the final value?

To find the solution, we first divide 4385 by 5, which gives us 877. Then, multiplying this result by 9, we obtain 7893. Therefore, the final value is 7893 when dividing 4385 by 5 and multiplying the quotient by 9.
