Math question: What is the sum of the digits in the number 3105?

To find the sum of the digits in the number 3105, we add each digit together: 3 + 1 + 0 + 5 = 9.

Math question: If the number 3105 is subtracted by the product of its first digit and the sum of its digits, what is the result?

The first digit of 3105 is 3, and the sum of its digits is 3+1+0+5=9. So, the product of the first digit (3) and the sum of digits (9) is 3x9=27. Finally, subtracting 27 from 3105 gives us 3078 as the result.

Math question: What is the largest prime factor of the number 3105?

To find the largest prime factor of 3105, we start by checking smaller prime numbers. Dividing 3105 by 2 gives us 1552.5, not a whole number. Then dividing it by 3 gives us 1035, which is divisible by 5 resulting in 207. Finally, dividing 207 by 3 gives us 69, which is divisible by 23. The process ends here because 23 is a prime number. Hence, the largest prime factor of 3105 is 23.
