Math Question: What is the square root of the sum of 2556 divided by 2, multiplied by the difference between 2556 and the product of its digits?

To find the answer, we first calculate the sum of the digits of 2556, which is 2 + 5 + 5 + 6 = 18. Next, we determine the difference between 2556 and its digit product, which is 2556 - (2 * 5 * 5 * 6) = 2446. Dividing the sum of 2556 by 2 gives us 2556/2 = 1278. Finally, multiplying 1278 by 2446 and finding the square root yields √(1278 * 2446) ≈ 1907.52. Thus, the square root of the sum of 2556 divided by 2, multiplied by the difference between 2556 and the product of its digits is approximately 1907.52.

Math question: What is the sum of the digits in the number 2556?

To find the sum of the digits, we add the value of each individual digit in 2556. 2 + 5 + 5 + 6 = 18 Thus, the sum of the digits in the number 2556 is 18.

Question: What is the sum of the prime factors of the number 2556?

To find the prime factors of 2556, we start by dividing it by the smallest prime number, 2. We get 2556 ÷ 2 = 1278. As 1278 is also divisible by 2, we divide it again to get 1278 ÷ 2 = 639. Continuing this process, we find that 639 ÷ 3 = 213, 213 ÷ 3 = 71, and 71 is a prime number. Thus, the prime factors of 2556 are 2, 2, 3, 3, and 71. The sum of these prime factors is 2 + 2 + 3 + 3 + 71 = 81.
