Math Question: What is the sum of the digits of the number 2641?

To find the sum of the digits of the number 2641, we add each digit together: 2+6+4+1=13. Therefore, the sum of the digits is 13.

Math question: What is the largest prime factor of the number 2641?

To find the largest prime factor of 2641, we start by checking divisibility by prime numbers. Since 2641 is odd, it's not divisible by 2. We check 3: 2641 ÷ 3 = 880.333 (not divisible). Next, we check division by 5, 7, 11, and 13 - none are divisible. Moving on to 17: 2641 ÷ 17 = 155.352941 (not divisible). Continuing this process, we divide by larger prime numbers such as 19, 23, 29, 31, etc. until we find the largest prime factor. Eventually, we discover that 2641 does not have any prime factors larger than itself. Hence, the largest prime factor of 2641 is 2641 itself.

Question: What is the sum of the digits in the number 2641 and the result of multiplying it by the difference between the largest and smallest digit?

To find the sum of the digits in 2641, we add 2 + 6 + 4 + 1 = 13. The difference between the largest (6) and smallest (1) digit is 6 - 1 = 5. Now, we multiply 13 by 5 to get the final result, which is 13 * 5 = 65. Thus, the answer is 65.
