Math question: Find the largest prime factor of the number 7877.

To find the largest prime factor of 7877, we start by dividing it by the smallest prime number, 2. The result is not an integer. Next, we try division by 3, which leaves a remainder of 1. Continuing this process, we divide by 5, 7, 11, 13, 17, and so on until we reach a divisor greater than the square root of 7877, which is approximately 88.8. After several attempts, we find that 7877 is divisible by 59, yielding a quotient of 133. Therefore, 7877 = 59 × 133. Hence, the largest prime factor of 7877 is 59.

Math Question: What is the sum of the digits in the number 7877 when each digit is squared and multiplied by its position from the right (units digit = 1, tens digit = 2, etc.)?

To find the sum, we square each digit and multiply it by its respective position: (7^2 x 4) + (8^2 x 3) + (7^2 x 2) + (7^2 x 1) = (49 x 4) + (64 x 3) + (49 x 2) + (49 x 1) = 196 + 192 + 98 + 49 = 535. Therefore, the sum of the digits in the number 7877, when each digit is squared and multiplied by its position, is 535.

Math question: What is the remainder when 7877 is divided by 9?

To find the remainder when dividing 7877 by 9, we sum its digits: 7+8+7+7=29. Then, we repeat the process with the new number: 2+9=11. Finally, we repeat it once more: 1+1=2. Therefore, the remainder is 2.
