Math Question: What is the smallest prime number that can divide 2,812 without leaving any remainders?

To find the smallest prime number that can divide 2,812, we start by checking the divisibility by prime numbers. We divide 2,812 by 2, but it leaves a remainder of 0. Continuing onwards, we divide by 3, 5, 7, 11, and 13, but all these prime numbers leave a remainder. Finally, when we divide 2,812 by 17, it evenly divides without any remainders. Hence, the smallest prime number that can divide 2,812 is 17.

Math question: What is the sum of the digits of the number 2812?

To find the sum, we add up the individual digits of 2812: 2 + 8 + 1 + 2 = 13.

Math Question: What is the product of the sum of the digits of 2812, divided by the difference between the highest and lowest digit?

To find the sum of digits, we have 2+8+1+2 = 13. The highest digit is 8, and the lowest is 1. Thus, the difference is 8-1 = 7. Now, the product of the sum of digits divided by the difference is (13/7) = 1.8571428571 (rounded to 10 decimal places).
