Math question: What is the smallest prime factor of 7791?

To find the smallest prime factor of 7791, we can start by checking divisibility by prime numbers up to the square root of 7791, which is approximately 88. The factors of 7791 are 1, 3, 7, 9, 21, 27, 63, 189, and 729. None of these are prime. Continuing with higher numbers, we eventually find that 7791 is divisible by 13, resulting in the factors 3 and 597. However, 3 is the smallest prime factor of 7791.

Math question: What is the sum of the digits in the number 7791?

To find the sum of the digits in the number 7791, we add each digit individually. The digit '7' contributes 7, the digit '7' contributes 7, the digit '9' contributes 9, and the digit '1' contributes 1. Adding them together, we get 7 + 7 + 9 + 1 = 24. Therefore, the sum of the digits in the number 7791 is 24.

Question: If I multiply 7791 by 3 and subtract 1734, what is the result when divided by 2 and added to the square root of 100?

Starting with the given number 7791, multiplying it by 3 gives 23,373. Subtracting 1734 from 23,373 yields 21,639. Dividing this by 2 gives 10,819.5. Additionally, the square root of 100 is 10. When we add these two values together, 10,819.5 + 10, the result is 10,829.5. Therefore, the final answer is 10,829.5.
