Question: What is the largest prime factor of the number 7941?

To find the largest prime factor of the number 7941, we first list out the prime numbers starting from 2: 2, 3, 5, 7, 11, 13, 17, ... Dividing 7941 by 2 results in 3970.5, which is not a whole number. Continuing, we divide 7941 by 3, giving us 2647. Dividing further, we find that 7941 divided by 7 is approximately 1134.42. Continuing this process, we divide by 11 and obtain approximately 721.90. Dividing by 13 gives us approximately 610.85. Finally, dividing by 17 yields approximately 467.71, which is the closest whole number. Therefore, the largest prime factor of 7941 is 17.

Math Question: The number 7941 is a 4-digit number. If we subtract the sum of its digits from the product of its digits, what is the resulting number?

To find the resulting number, we start by calculating the sum of the digits: 7 + 9 + 4 + 1 = 21. Then, we compute the product of the digits: 7 × 9 × 4 × 1 = 252. Finally, we subtract the sum of the digits from the product of the digits: 252 - 21 = 231. Therefore, the resulting number when we subtract the sum of the digits from the product of the digits in the number 7941 is 231.

What is the sum of the digit at the thousand's place, the product of the digits at the hundred's and ten's places, and the difference between the digit at the unit's place and the digit at the thousand's place in the number 7941?

The digit at the thousand's place is 7, the product of the digits at the hundred's and ten's places is 9 × 4 = 36, and the difference between the digit at the unit's place (1) and the digit at the thousand's place (7) is -6. Therefore, the sum of these three values is 7 + 36 + (-6) = 37.
