Math question: What is the sum of the digits in the number 7045?

To find the sum of the digits in 7045, we add each individual digit together. Starting from the left, 7 + 0 = 7, 7 + 4 = 11, 11 + 5 = 16. Therefore, the sum of the digits in 7045 is 16.

Question: What is the least common multiple of 7045 and 2?

To find the least common multiple (LCM) of two numbers, we need to determine the smallest multiple that both numbers share. Given that 7045 is an odd number and 2 is an even number, the LCM must be even because it must be divisible by 2. Therefore, the LCM of 7045 and 2 is 7046.

What is the sum of the digits in the number 7045 raised to the power of 3 and divided by the sum of the factors of the number 7045?

To solve the math problem, we first calculate the sum of the digits in 7045, which is 7 + 0 + 4 + 5 = 16. Then, we raise this sum to the power of 3, resulting in 16^3 = 4096. Next, we find the factors of 7045: 1, 5, 29, 145, and 49. The sum of these factors is 1 + 5 + 29 + 145 + 7045 = 7225. Finally, we divide our earlier result, 4096, by the sum of the factors, 7225, resulting in 4096/7225 ≈ 0.5674. Therefore, the answer is approximately 0.5674.
