Math question: What is the largest prime factor of the number 2951?

To find the largest prime factor of 2951, we first check if it is divisible by 2. Since it is odd, we move on to the next prime number, 3. Dividing 2951 by 3 gives 983. Next, we try dividing by 5, 7, 11, etc., until we reach 983. Upon testing division with prime numbers up to the square root of 983, we find that no larger prime numbers divide 983. Therefore, the largest prime factor of 2951 is 983.

Math question: What is the sum of the digits of the number 2951?

To find the answer, we need to add the individual digits of the number 2951. The digit 2 + the digit 9 + the digit 5 + the digit 1 equals 17. Hence, the sum of the digits of the number 2951 is 17.

What is the sum of all the even numbers between 1000 and 5000, excluding 2951?

The even numbers between 1000 and 5000 form an arithmetic sequence with a common difference of 2. Using the formula for the sum of an arithmetic series, we can find the number of terms: (5000 - 1000)/2 + 1 = 2001. To find the sum, we can use the formula: Sum = (number of terms/2) * (first term + last term). The first term is 1000, and the last term is 5000. So, the sum of all even numbers between 1000 and 5000, excluding 2951, is (2001/2) * (1000 + 5000) = 5,005,000.
