Math Question: If the number 1395 is multiplied by 7 and then divided by the sum of its digits, what is the result?

To find the sum of the digits of 1395, we add 1 + 3 + 9 + 5, which equals 18. Then, multiplying 1395 by 7 gives us 9765. Dividing 9765 by 18, the sum of the digits, yields the result 542.5.

Math Question: What is the sum of all the prime factors of the number 1395?

To find the prime factors of 1395, we begin by dividing it by 2, but as it is not divisible, we proceed to the next prime number, 3. By dividing 1395 by 3, we get 465. Now, dividing 465 by 3 gives 155. From here, dividing 155 by 5 yields 31, which is a prime number. Therefore, the prime factors of 1395 are 3, 3, 5, and 31. Adding them up, 3 + 3 + 5 + 31 = 42. Thus, the sum of all the prime factors of 1395 is 42.

Math question: Consider the number 1395. If we multiply it by 3 and divide the result by the sum of its digits, what is the final outcome?

To find the outcome, we first multiply 1395 by 3, which equals 4185. Now, we need to sum the digits: 4 + 1 + 8 + 5 = 18. Finally, we divide 4185 by 18 to get our answer. The result is approximately 232.5. Therefore, dividing the number 1395 by the sum of its digits gives us an outcome of approximately 232.5.
