Question: What is the maximum prime factor of the number 1787?

To find the maximum prime factor of 1787, we start by dividing it by the smallest prime number, which is 2. Since 1787 is an odd number, we move on to the next prime number, which is 3. After dividing 1787 by 3, we get 595.6667, which is not a whole number. Next, we try dividing 1787 by 5, but again, it is not divisible evenly. Continuing this process, we realize that 1787 is not divisible by 7, 11, 13, 17, or 19 either. Finally, we find that 1787 divided by 23 equals 77.9565, which is not a whole number. Therefore, the maximum prime factor of 1787 is 19 since there are no prime factors greater than 19 that divide evenly into 1787.

Math question: What is the sum of the digits in the number 1787?

To find the sum of the digits in 1787, we add the individual digits together: 1 + 7 + 8 + 7 = 23. Therefore, the sum of the digits in 1787 is 23.

Math question: If the number 1787 is tripled, divided by 2, and then subtracted by 10, what is the result?

To find the result, we first triple 1787, which yields 5361. Then, dividing 5361 by 2 gives us 2680.5. Finally, subtracting 10 from 2680.5 gives a final result of 2670.5. Therefore, the final result of the given operations on the number 1787 is 2670.5.
