Math question: If 3645 is divided by the sum of its digits subtracted by twice its tens digit added to its units digit, what is the quotient?

To solve, we need to find the sum of the digits (3+6+4+5=18), then subtract twice the tens digit (2*6=12) added to the units digit (12+5=17). So, subtracting 17 from 18 gives us 1. Now, dividing 3645 by 1, the quotient is 3645 itself. Therefore, the quotient is 3645.

What is the largest prime factor of the number 3645?

To find the prime factorization of 3645, we can start by dividing it by the smallest prime number, which is 2. However, 3645 is not divisible by 2. Next, we try dividing it by 3. 3645 divided by 3 gives us 1215. Again, we continue dividing 1215 by 3, resulting in 405. Continuing this process, 405 divided by 3 gives us 135. Lastly, dividing 135 by 3 gives us 45. Now, 45 is not divisible by 3, so we move on to the next prime number, 5. Dividing 45 by 5 gives us 9, which is also divisible by 3. Dividing 9 by 3 gives us 3. Therefore, the prime factorization of 3645 is 3 x 3 x 3 x 5 x 5 x 5. The largest prime factor is 5, so that is our answer.

Math Question: What is the sum of the digits in the number 3645?

To find the sum of the digits in 3645, we add the individual digits together. Starting from the left, we have 3 + 6 + 4 + 5, which equals 18. Therefore, the sum of the digits in the number 3645 is 18.
