Math question: What is the product of the prime factors of the number 1615?

Prime factorize 1615: 1615 = 5 × 17 × 19. Thus, the product of the prime factors of 1615 is 5 × 17 × 19 = 1615.

Math question: What is the sum of all the even numbers between 1500 and 1700 inclusive?

To find the sum of even numbers between 1500 and 1700, we first determine the number of even numbers in this range. Since the last even number (1700) and the first even number (1500) differ by 200, we divide this difference by 2 (as the difference between consecutive even numbers is 2) and add 1 (since both endpoints are inclusive). Thus, (1700 - 1500) / 2 + 1 = 101. Next, we can find the average of the first and last number (1500 + 1700) / 2 = 1600. And now multiplying the average by the number of even numbers (101) gives us 161,600. Therefore, the sum of all the even numbers between 1500 and 1700 is 161,600.

Question: Find the remainder when the number 1615 is divided by the sum of its digits multiplied by the difference between its tens and units digit, all squared.

To find the remainder when 1615 is divided by the sum of its digits (1+6+1+5=13) multiplied by the difference between its tens and units digit (6-5=1), we have to find the value of (13*1)^2. Simplifying this, we get (13)^2 = 169. Now, when 1615 is divided by 169, the remainder can be calculated as the difference between the dividend and the quotient multiplied by the divisor. Let's find the quotient first, which is 1615 divided by 169 equals 9. The remainder is then obtained by (1615 - 9*169) = 1615 - 1521 = 94. Therefore, the remainder when 1615 is divided by the sum of its digits multiplied by the difference between its tens and units digit, all squared, is 94.
