Math question: What is the largest prime factor of 2681?

To find the largest prime factor of 2681, we can start by checking if it is divisible by any prime numbers. Dividing 2681 by 2, we get 1340 with a remainder. Continuing the process, we find that it's not divisible by 2, 3, 5, or 7. However, dividing by 11 gives a quotient of 243, which is a perfect cube. So dividing by 11 again, we find the quotient to be 22. Clearly, 2681 is not divisible by any prime larger than 11. Thus, the largest prime factor of 2681 is 11.

Math question: What is the sum of the digits in the number 2681?

To find the sum of the digits, we add the individual values together. The digit 2 has a value of 2, the digit 6 has a value of 6, the digit 8 has a value of 8, and the digit 1 has a value of 1. So, 2 + 6 + 8 + 1 = 17. Hence, the sum of the digits in the number 2681 is 17. This means that if you add up all the digits in the number 2681, the result is 17.

What is the largest prime factor of the number 2681?

In order to find the largest prime factor of the number 2681, we need to factorize it. By dividing 2681 successively by prime numbers starting from 2, we find that 2681 equals 7 multiplied by 383. Since 383 is a prime number, it is the largest prime factor of 2681. Therefore, the answer is 383.
