Math question: What is the product of 915 multiplied by its double, added to the sum of 915 squared and one-third of 915?

To find the product of 915 multiplied by its double, we calculate 915 × 2 = 1830. Next, we determine the square of 915, which gives us 915 × 915 = 837225. Lastly, one-third of 915 is 915/3 = 305. Now, we add the calculated values: 1830 + 837225 + 305 = 839360. Thus, the answer is 839360.

What is the sum of all prime factors of the number 915?

The prime factorization of 915 is 3 * 3 * 5 * 17. Adding up these prime factors, we get 3 + 3 + 5 + 17 = 28. So, the sum of all prime factors of 915 is 28.

Math question: What is the largest eight-digit number that is divisible by 5 and contains the digits 9, 1, and 5 only, using each digit once?

The largest eight-digit number divisible by 5, using the digits 9, 1, and 5 exactly once, is 951,800. To find this, we start with the given digits 9, 1, and 5 and notice that the number must end with either 0 or 5 to be divisible by 5. Then, we arrange the remaining digits (9 and 1) in a way that creates the largest possible number. Since the number is in the millions place, it must be larger than the smallest eight-digit number (10,000,000). To maximize the value, we place 9 in the millions place, 1 in the hundred thousands place, 5 in the ten thousands place, and 8 in the thousands place. Finally, since our target number must be divisible by 5, we allocate the remaining 0 in the units place. Therefore, the largest eight-digit number satisfying these conditions is 951,800.
